Quick Facts

Where Is Sienna Spiro From?

Sienna Spiro is from London, England, where she was born on 28 September 2005. She was raised in the city and educated there — first at Francis Holland School in Sloane Square, then at East London Arts & Music, before leaving school at 16 to pursue music full-time. London’s influence shows up throughout her career: her first live performance took place at a pub near Heathrow, and she’s spoken about the city’s music scene as a formative backdrop to her songwriting.

How Old Is Sienna Spiro?

Sienna Spiro was born on 28 September 2005, which makes her 20 years old as of 2026. She started writing songs at just 10 years old and had already built a large TikTok following by the time she was 16 — meaning most of her public career so far has happened while she was still a teenager.

Sienna Spiro’s Family

Who Are Sienna Spiro’s Parents?

Sienna Spiro’s father is Glenn Spiro, one of the world’s most respected fine jewellers. Born on 1 June 1962 in East London, Glenn grew up in a working-class household and left school at 14 with no formal qualifications — a background he’s been candid about in interviews. He went on to found the jewellery house G. Collins and Sons, known for one-of-a-kind pieces using rare diamonds and coloured stones, and has designed jewellery worn by figures including Beyoncé, Jay-Z, Rihanna, Gwyneth Paltrow, Zendaya, and the Princess of Wales. Notably, Glenn created a yellow diamond ring named the “Sienna Diamond” after his daughter, which later sold at auction for $3.4 million, as well as a sapphire and diamond pendant called the “Arabella,” named after his wife.

Sienna’s mother is Arabella Spiro (née Bodie). She is closely involved with Tikva UK, a non-profit organisation that supports at-risk Jewish children in Ukraine, Romania, and Israel — work that reflects the family’s Jewish faith and values, which Sienna has said shaped her upbringing.

Does Sienna Spiro Have Siblings?

Yes. Sienna has three siblings: an older brother named Joe, who is in his early thirties and works within the family jewellery business alongside their father, and two sisters, Talia and Skylar (also spelled Skyla). Joe is from Glenn’s earlier relationship, while Talia is Sienna’s full sister through Arabella and Glenn. Exact public birthdates for her siblings haven’t been confirmed, so precise ages beyond Joe’s have not been independently verified — but all three have largely stayed out of the public eye compared to Sienna’s music career.

Sienna has described growing up in a household immersed in music and film from an early age — her father introduced her to Frank Sinatra, Nina Simone, Etta James, and classic Italian cinema, influences that come through clearly in her sound today.

Sienna Spiro Before Fame

Before the viral videos and chart singles, Sienna Spiro was a schoolgirl writing songs in her bedroom. She began writing at age 10, starting with a track called “Lady in the Mirror,” and gave her first live performance shortly after at a pub near Heathrow. She attended Francis Holland School before transferring to East London Arts & Music, a specialist performing arts college — and left formal education altogether at 16 to commit to music full-time, a decision that mirrors her father’s own early departure from school.

Her real public turning point came in 2021, when she started posting singing videos on TikTok. Covers and original material steadily built a large following, laying the groundwork for her first official releases in 2024 — well before most listeners had heard her name.

Career: From TikTok to the Charts

Spiro began officially releasing music in 2024, with the single “Maybe” marking her first entry on the UK Singles Chart. Her debut EP, Sink Now, Swim Later, followed in February 2025.

Her real breakthrough came with “Die on This Hill” in October 2025, which reached the UK top 10, was used more than eight million times on TikTok, and led to a global publishing deal with Sony Music Publishing. Momentum carried into 2026: a BRIT Awards Critics’ Choice nomination, a performance on The Tonight Show Starring Jimmy Fallon, a surprise duet with Sam Smith, a performance for Sir David Attenborough’s 100th birthday at the Royal Albert Hall, and her debut studio album, Visitor, released on 3 July 2026.

Musical Style

Spiro’s sound blends jazz, soul, and contemporary pop, built around piano-driven arrangements and expressive, largely one-take vocal recordings. Critics have compared her voice and aesthetic — a 1960s-inspired beehive hairstyle, thick eyeliner, vintage clothing — to Adele, Amy Winehouse, and Lana Del Rey. Her own stated influences, including Etta James, Nina Simone, and Frank Sinatra, come through clearly in the vintage, emotionally direct feel of her songs. She frequently collaborates with Jewish Israeli producer Omer Fedi, who she credits with encouraging her stripped-back, human style of recording.

What’s Next

With her debut album out and an international touring schedule underway, Spiro’s 2026 has moved her from viral TikTok artist to a genuine international act.
