Billie Paul Piper (born Leian Paul Piper; 22 September 1982) is an English actress and former singer. She initially gained recognition as a singer after releasing her debut single "Because We Want To" at the age of 15, which made her the youngest female singer to enter the UK Singles Chart at number one. Her follow-up single "Girlfriend" also entered at number one. In 1998, Piper released her debut studio album, Honey to the B, which was certified platinum by the British Phonographic Industry (BPI). Her second studio album, Walk of Life, was released in 2000 and spawned her third number-one single, "Day & Night". In 2003, Piper announced that she had ended her music career to focus on acting.
Piper appeared in the BBC One sci-fi series Doctor Who as Rose Tyler, companion to The Doctor, as a regular from 2005 and 2006, and made guest appearances in 2008 and 2010. She made further appearances in the series' 50th anniversary special (2013) as "The Moment", though still credited as Rose Tyler, and in "The Reality War" (2025) in an unnamed role.
She starred as Belle de Jour in the drama series Secret Diary of a Call Girl (2007–2011), as Brona Croft/Lily in the Showtime horror series Penny Dreadful (2014–2016), and as Karen Mars in Netflix Original series Collateral (2018), for which she was nominated for a British Academy Television Award for Best Supporting Actress. Piper co-created and starred in the Sky Atlantic series I Hate Suzie (2020–2022), for which she earned a BAFTA nomination for Best Actress in 2021 and 2023. In 2025 she began starring as Isadora Capri, in the Netflix comedy-horror series Wednesday.
Piper's performance in Yerma won both the 2017 Laurence Olivier Award for Best Actress in a Leading Role in a Play and the 2016 Evening Standard Theatre Award for Best Actress for her "breathtakingly-intense" critically-acclaimed performance. The Guardian described Piper as "one of the most exciting stage actors of her generation."
Piper was born in Swindon, Wiltshire, on 22 September 1982. She was initially named Leian Paul Piper, but her first name was legally changed to Billie on 25 April 1983 by her parents, Mandy Kent and Paul Piper. She has three siblings. Piper started dance classes aged five. Two years later, she appeared in soft-drink commercials for American TV before taking a role as an extra in the 1996 film Evita. She attended Bradon Forest School in Purton, near Swindon, but left at around the age of 12 after winning a scholarship to the Sylvia Young Theatre School in London.
Piper's career began when she was selected to appear on the Saturday morning children's television show Scratchy & Co. She later landed a role in a television commercial promoting the pop magazine Smash Hits. She was offered a record deal at the age of 15, and in 1998, became the youngest artist to debut at number one in the UK Singles Chart with "Because We Want To", released under the stage mononym "Billie". Her follow-up single "Girlfriend" also debuted at number one.
Piper's debut album Honey to the B was released immediately afterwards, and entered and peaked at number 14 on the UK Albums Chart, selling more than 300,000 copies in the United Kingdom alone along with a platinum certification, and a double-platinum certification in New Zealand, where it peaked at number three on the New Zealand Albums Chart. However, Honey to the B found limited success in other territories, such as Australia, where it entered and peaked at number 31 on the ARIA Albums Chart despite the success of "Honey to the Bee", and in the US it went almost completely unnoticed, peaking at number 17 on the Billboard Heatseekers Chart.
At the 1998 Smash Hits Poll Winners' party, Piper was nominated for Best New Act (for which she came second, it being won by B*Witched) and won Princess of Pop (she was the first to win this award). She then released "She Wants You" as the third single from the album. The song reached number three. "Honey to the Bee" was released as the fourth single from the album; like the previous single, it reached number three. At the same time, "She Wants You" was released in the US, reaching number 9 on the "Hot Club Dance Play" chart.
In 1999, Piper was nominated for two BRIT Awards and won two awards at the 1999 Smash Hits Poll Winners' party, although she was reduced to tears at the latter ceremony after being booed by fans of Ritchie Neville, whom she was dating at the time. She then started to tour and release in Asia. The singles and the album were released in mid- to late 1999. In August of that year, the follow-up to "Because We Want To" was released in Japan, a single comprising "Girlfriend" and "She Wants You" combined. She recorded a song for Pokémon: The First Movie titled "Makin' My Way (Any Way That I Can)".
During that time, Piper recorded her second album. She decided to release further records under her full name of Billie Piper. She returned to the Singles Chart in May 2000 with her third number-one single "Day & Night". She waited until September to release "Something Deep Inside", which reached number four, but her success waned. In October 2000, Piper released her second album, Walk of Life, which reached No. 14 in the UK Album Chart, but quickly fell off the charts and was certified silver in the UK. The album charted in two other countries: New Zealand, where it reached No. 17, and Australia, where it peaked at No. 23. In Piper's autobiography, she states that the album was a "commercial bomb". The song "Walk of Life", the final single off the album, was released in December 2000 and reached No. 25 in the UK Singles Chart.
In February 2001, Piper appeared in court to testify against a woman named Juliet Peters. Peters was charged with, and eventually convicted of, stalking as well as making numerous threats against Piper and members of her family. Peters received psychiatric treatment as part of her sentence. According to her autobiography, Piper was reluctant about the court case, but was pushed by her parents and her label. She also stated in the book that this was why "The Tide Is High" was not released as a single, writing: "The court case succeeded in doing what I alone could not – cutting the ties. Without it I might have been tempted back."
In January 2007, BBC Radio 1 DJ Chris Moyles started a campaign to get "Honey to the Bee" back into the top 100 on download sales as a way of testing out new chart rules that favour download sales. The campaign was successful, with "Honey to the Bee" re-entering the official UK singles chart at No. 17, eight years after it was first released.
Film and television performances
In 2004, Piper appeared in the films The Calcium Kid and Things to Do Before You're 30. Shortly before starting work on Doctor Who, she had a starring role in the horror film Spirit Trap, released in August 2005 to poor reviews. In November 2005, she starred as Hero in a BBC adaptation of Much Ado About Nothing, updated for the modern day in a similar manner to the Canterbury Tales (2003) series in which she featured, with Hero now being a weather presenter in a television station.
In 2005, Doctor Who was resurrected after a sixteen-year absence from TV. Piper was cast as Rose Tyler, a travelling companion to the ninth incarnation of The Doctor (played by Christopher Eccleston). Piper won the Most Popular Actress category at the 2005 and 2006 National Television Awards for her work on Doctor Who. BBC News named her one of its "Faces of the Year" for 2005, primarily due to her success in Doctor Who. At The South Bank Show Awards in January 2006, she was awarded The Times Breakthrough Award for her successful transition from singing to acting. In March, the Television and Radio Industries Club named her as the best new TV talent at their annual awards ceremony. In September, she was named Best Actress at the TV Quick and TV Choice Awards.
After the completion of the very successful first series of the revamped Doctor Who, the British media regularly released conflicting reports about how long Piper would be staying with the show. In March 2006, she claimed that she would continue on Doctor Who into its third series in 2007. In May, however, she was reported to be considering quitting the series, although she did express an interest in playing a female version of the Doctor in the future (possibly related to a proposed Doctor Who spin-off series about Rose, which was later dropped). In June, the BBC announced that she was to depart in "Doomsday" (2006), the final episode of the second series. Her decision to leave had been made a year previously, but had not yet been made public.
