Sienna Spiro is a 20-year-old British singer-songwriter from London who went from posting TikTok covers in her bedroom to performing on The Tonight Show Starring Jimmy Fallon, earning a BRIT Awards Critics Choice nomination, landing on Forbes 30 Under 30, and releasing her debut album Visitor in July 2026, all within the space of roughly two years. Her breakthrough single “Die on This Hill” has amassed over 800 million total Spotify streams, and critics have compared her powerful contralto voice to Adele and Amy Winehouse. Below is everything you need to know about Sienna Spiro.
Who Is Sienna Spiro?
Sienna Spiro is a British singer-songwriter and record producer born in London, England, to a Jewish family with strong roots in both art and philanthropy. She is the daughter of Glenn Spiro, one of the world’s most celebrated fine jewellers, and Arabella Spiro, who is actively involved with Tikva UK, a charity supporting at-risk Jewish children in Ukraine, Romania, and Israel.
Sienna began writing songs at the age of ten, influenced from the very start by jazz and soul legends including Etta James, Frank Sinatra, Frank Ocean, and Amy Winehouse. She attended two schools in London before dropping out at sixteen to pursue music full time, a decision that has been thoroughly vindicated by everything that followed.
She built her early following on TikTok from 2021 onwards, starting with viral cover videos, then releasing original music from 2024. By January 2026, she was standing on the stage of The Tonight Show Starring Jimmy Fallon with a 12-piece string ensemble, delivering a performance of “Die on This Hill” that left Jimmy Fallon speechless and the studio audience on their feet. Rolling Stone UK described her voice as “packed with power” that “stealthily belies her 20 years.”

Sienna Spiro Age: How Old Is She in 2026?
Sienna Spiro is 20 years old in 2026. She was born on September 28, 2005, in London, England. She is a Libra. It is worth pausing on just how young she is relative to everything she has already achieved. She dropped out of school at sixteen. By seventeen, she was going viral on TikTok. By eighteen, she had signed with Capitol Records. By nineteen, she had her first UK Top 10 hit with “Die on This Hill.” And at twenty, she has a Forbes 30 Under 30 listing, two American Music Award nominations, and a debut album out on one of the world’s biggest labels.
Early Life and Family Background
Sienna Spiro was born on September 28, 2005, in London, England. She grew up in a household shaped equally by creativity, faith, and public service. She has three siblings: a brother named Joe and two sisters named Talia and Skyla.
Her father is Glenn Spiro, one of the most respected fine jewellers in the world. Glenn founded his jewellery house G. Collins and Sons and is known internationally for creating one-of-a-kind pieces incorporating extraordinarily rare diamonds and coloured stones. He created a yellow diamond ring that he named the Sienna Diamond after his daughter. That ring was later sold at auction for $3.4 million. He also designed a sapphire and diamond pendant named the Arabella, after Sienna’s mother. His work sits in some of the most significant private collections in the world. Glenn’s prominence in the jewellery world means Sienna grew up around artistry, craftsmanship, and an understanding that extraordinary dedication to a single creative discipline can define a life.
Her mother is Arabella Spiro, who has been actively involved with Tikva UK for many years. Tikva UK is a non-profit organisation that supports Jewish children at risk in Ukraine, Romania, and Israel, providing education, care, and community for vulnerable young people. Arabella’s charitable commitment has shaped Sienna’s own strong sense of social responsibility.
Sienna is Jewish and has spoken about her faith and family background as central to her identity.
She began writing songs at the age of ten, drawing inspiration from musicians including Etta James, Frank Sinatra, Frank Ocean, and early-2000s hip-hop artists. This combination of jazz-era soul and contemporary influence is precisely what gives her music its distinctive character: it sounds rooted and timeless in a way that most pop releases do not.
Sienna Spiro Education
Sienna attended Francis Holland School, Sloane Square, one of London’s most respected independent girls’ schools, before moving to East London Arts and Music (ELAM), a specialist music college that has produced a number of significant UK artists. At sixteen, she made the decision to drop out of formal education entirely to pursue her music career full time. That decision required both confidence and courage, but it reflects the same single-minded commitment to craft that her father brought to jewellery and that the artists she admired brought to their music.
Sienna Spiro Career
TikTok and Early Viral Growth (2021 to 2023)
In 2021, Sienna began posting videos of herself singing on TikTok under the handle @siennaspiro. Her first viral moment came in November 2022, when her performance of “Read All About It” gained over four million views and introduced her to a much wider audience. Through 2023, she continued posting a mix of covers and original material, steadily building a following that reached over two million on the platform.
What set her apart from the thousands of other vocalists posting on TikTok was immediately obvious to anyone who listened: her voice. A deep, rich contralto with an emotional directness that felt far older than her age, it drew comparisons to Amy Winehouse and Adele from the earliest days of her online presence.
“Need Me” and “Maybe” (2024)
Sienna released her debut single, “Need Me”, on May 24, 2024, marking her official transition from viral creator to signed recording artist. She signed with Capitol Records, one of the world’s most storied music labels, home to artists including Katy Perry, Sam Smith, and Coldplay.
Her second single, “Maybe”, followed in August 2024. The song peaked at No. 45 on the Official UK Singles Chart and became her first commercial chart entry. It later surpassed 105 million Spotify streams, topped four viral Spotify charts globally, and launched her first late-night television appearance, a performance on The Late Show with Stephen Colbert in June 2025. She also performed at the All Points East festival at Victoria Park in London in August 2024, her first major festival appearance.
After the release of “Back to Blonde” in November 2024, music publication Dazed named her a “musician to watch” for 2025.
Sink Now, Swim Later EP (February 2025)
In January 2025, Sienna released “Butterfly Effect”, a standout track built around ascending piano lines and sweeping strings that explores regret and consequence. The song captures the emotional tone of the EP that followed: introspective, lush, and genuinely affecting.
Her debut EP Sink Now, Swim Later arrived on February 2025 under Capitol Records. The eight-track project focused on relationships and young adulthood and was the record that firmly established her as more than a viral singer. It has since surpassed 122 million streams. She then released “Dream Police” in May 2025 and “You Stole the Show” in July 2025, before embarking on her first UK headline tour in September 2025.
“Die on This Hill” (October 2025)
In October 2025, Sienna released “Die on This Hill”, and everything changed. The song is a soulful pop ballad about stubborn love, specifically the kind where someone stays in a relationship despite knowing they should leave, holding onto pride and determination rather than walking away. Built around haunting piano lines and sweeping strings, it perfectly showcases the depth of her contralto voice.
The track became her defining breakthrough, reaching No. 9 on the UK Singles Chart, debuting at No. 69 on the Billboard Hot 100, and amassing over 145 million global Spotify streams within weeks. It reached No. 23 on Spotify’s US chart and No. 47 globally. The song sold over 4 million copies worldwide.
Following the release, Sienna signed a global publishing agreement with Sony Music Publishing, one of the most significant deals available to an independent artist of her profile.
The Tonight Show Starring Jimmy Fallon (January 8, 2026)
On January 8, 2026, Sienna made her US late-night television debut on The Tonight Show Starring Jimmy Fallon, performing “Die on This Hill” accompanied by a piano and a 12-piece string ensemble. She wore a custom dress for the occasion that incorporated a vintage image of original Tonight Show host Johnny Carson, a beautifully considered nod to late-night television history.
The performance left Jimmy Fallon visibly stunned. He responded by saying: “Oh my goodness, wow! That’s how you do it, are you kidding me? You are amazing! Standing O, not too shabby. You are fantastic.” The studio audience gave her a standing ovation. Fan reaction online was instant and overwhelming, with many calling it one of the best late-night vocal performances in recent memory.
Sienna shared her feelings on Instagram after the performance: “Don’t have many words as to what this meant to me and how surreal it was. Thank you so much to everyone on the team who made this happen. So grateful and blessed to get to work alongside you all. I can’t believe this is my life, I am so truly grateful.”
Sam Smith Duet and Other Highlights (2026)
After her tour’s Los Angeles stop, Sienna joined Sam Smith on stage at San Francisco’s Castro Theatre for a surprise live duet of “Die on This Hill,” a moment that generated enormous attention across social media. In another surprise, P!nk covered “Die on This Hill” while hosting The Kelly Clarkson Show, a significant endorsement from one of pop music’s most respected live performers.
On May 8, 2026, Sienna performed a live rendition of “Nature Boy” at the Royal Albert Hall as part of the celebrations marking broadcaster and conservationist David Attenborough’s 100th birthday, an extraordinary invitation for any artist, let alone a 20-year-old in just her second year of releasing music.
She was also named Apple Music’s Up Next UK artist for November 2025, featured on the cover of Notion Magazine, and received critical acclaim from Rolling Stone, Dazed, the LA Times, V Magazine, The New York Times, The Hollywood Reporter, ELLE, and NYLON.
Additionally, she wrote the song “Material Lover” exclusively for The Devil Wears Prada 2 soundtrack, connecting her music to one of the most anticipated film releases of 2026.
BRIT Awards Critics Choice 2026
Sienna was nominated for the Critics Choice award at the 2026 BRIT Awards, one of the most important recognitions the UK music industry offers to emerging artists. Previous winners of this category include Adele, Florence and the Machine, Ellie Goulding, Sam Smith, Sam Fender, and Wet Leg. The nomination placed her firmly in the conversation as one of the most significant new voices in British music.
Forbes 30 Under 30 and American Music Awards (2026)
Sienna was named in Forbes 30 Under 30 for 2026 across the music and entertainment categories. She also received two 2026 American Music Award nominations: Best Vocal Performance and Breakthrough Pop Artist.
Debut Album: Visitor (July 3, 2026)
Sienna’s debut studio album Visitor was released on July 3, 2026, under Capitol Records. The album title reflects a theme of arrival, of entering spaces, relationships, and stages of life as a temporary but meaningful presence. In tandem with the album release, she announced her 40-date My House World Tour, covering North America, Asia, Australia, New Zealand, the UK, and Europe.
Her festival schedule for 2026 includes performances at Montreux Jazz Festival, All Points East, Lollapalooza, Newport Jazz Festival, Outside Lands, All Things Go, and Austin City Limits, a lineup that spans continents and confirms her status as a genuine international live act.
Sienna Spiro Musical Style
Sienna’s music sits at the intersection of soul, jazz, and contemporary pop. Her earliest inspirations were Frank Sinatra, Etta James, Amy Winehouse, and Frank Ocean, and those influences are audible in everything she makes. She blends classic soul arrangements with modern production, creating music that feels simultaneously vintage and completely current. Fashion and culture outlets including Interview Magazine have highlighted her distinct 1960s vintage aesthetic, noting style influences from Nancy Sinatra, Barbra Streisand, and Francoise Hardy. Critics at Official Charts, after attending her intimate show at The Tabernacle in Notting Hill, London, predicted that her career would sit alongside the legends who inspired her.

Outside of music, she has a pet dog that has appeared in her TikTok videos and has become a minor fan favourite in its own right. Her values are shaped by her Jewish faith and by her mother’s long involvement with Tikva UK.
Sienna Spiro Net Worth
