->''"There's not enough money in the world to get me singing 'Because We Want To' again."''

Billie Paul Piper (born Leian Paul Piper in Swindon, England, September 22, 1982) is an English actress and former singer, as well as the only full-time ''Series/DoctorWho'' companion to have three UK number-one hits to her name. She is notable for her dyed blonde hair and distinct black eyebrows.

Piper started out as an actress but moved into singing, with "Because We Want To" making her (at fifteen) the youngest singer to debut at No. 1. After two more, her star faded somewhat -- but in the middle of a lot of chaos, she married British presenter Radio/ChrisEvans (no, not that Creator/ChrisEvans). The marriage lasted for six years, and the [[AmicableExes two remain good friends]].

In 2003, she returned to acting, appearing in a modern version of ''The Miller's Tale'' (from ''Literature/TheCanterburyTales''). In 2004, she was cast in the revived ''Series/DoctorWho'' as Rose Tyler, [[TheWatson one of the many companions]], and the first one when the TV show returned from its hiatus in 2005. She reappeared as Rose after her 2006 departure in the last three episodes of the 2008 season, made a cameo in Creator/DavidTennant's [[Recap/DoctorWhoS30E17E18TheEndOfTime final episode]], and portrayed "The Moment", the sentient interface of the weapon the [[Creator/JohnHurt War Doctor]] used to (supposedly) destroy Gallifrey in the 50th Anniversary episode, [[Recap/DoctorWho50thASTheDayOfTheDoctor "The Day of the Doctor"]].

After her departure from ''Who'', she made further screen appearances, most notably as Literature/SallyLockhart in two film adaptations (alongside Creator/MattSmith) as well as ''Series/SecretDiaryOfACallGirl'' (where Matt Smith ''also'' showed up). Her first non-BBC TV role was as the star of ITV's adaptation of ''Literature/MansfieldPark''. She also gave a critically-praised performance in Creator/NeilLaBute's play ''Reasons to Be Pretty'', and made her debut at the National Theatre in ''The Effect''. She subsequently starred in the Showtime GothicHorror series ''Series/PennyDreadful'' as tubercular sex worker Brona Croft. In 2016-7, she reached new heights of critical praise as a theatre actor in the very demanding main role of Creator/FedericoGarciaLorca's play ''Yerma''. For this role, she won just about every British stage acting award and several American ones, and received the distinction of being the only actress to have won six out of an available six Best Actress awards in British theatre for a single performance[[note]]Critic's Circle Theatre Awards, Drama Desk Awards, Drama League Awards, Evening Standard Theatre Awards, the Lawrence Olivier Award, the Whatsonstage.com Awards, the Broadway World Theatre Awards, and the Glamour Award[[/note]].

She grew beyond acting with the romantic black comedy film ''Rare Beasts'', which she wrote and directed in addition to playing a major role in. In 2020, she co-created the TV series ''Series/IHateSuzie'' with Lucy Prebble, the main writer of ''Secret Diary of a Call Girl'', in which she plays an actress whose life spirals out of control after a sex-tape scandal -- many reviewers noted the parallels between the fictional Suzie's career and [[AdamWesting Piper's own]].

Piper also appeared on ''Series/TopGear'' as a "star in a reasonably priced car," where she confessed a love of classic cars and then drove round the track in an impressive 1 minute, 48.3 seconds.[[note]]She did cut corners though. A lot. Creator/DavidTennant complained about it during his appearance. A lot. [[DirtyOldMan Jeremy Clarkson]] responded by citing the transparent shirt that she was wearing at the time.[[/note]]

She married actor Laurence Fox in December 2007; with him, she has two sons, Winston James and Eugene Pip. They divorced in 2016. She began dating musician Johnny Lloyd the same year; with him, she has one daughter, Tallulah.

!!Tropes associated with her:
%%* DyeHard
* GenderBlenderName: Not just her forename, but her middle name as well (Paul).
** Although "Billie" is the female version of "Billy," but it sounds no different.
* IAmNotSpock: Billie Piper says she is often mistaken for Belle du Jour.
%%* IdolSinger
* MsFanservice: Ms. Piper is not shy about appearing in (and out of) sexy outfits.
* OldShame: She's not going to be belting out into "Because We Want To" anytime soon.[[note]]She's way more sport about it than others, however, as seen in ''Series/TheGrahamNortonShow'' (even [[SelfDeprecation taking the mickey on herself about it]]).[[/note]]
* TransAtlanticEquivalent: Ever since ''Doctor Who'' and ''Secret Diary'' started to pick up steam in terms of popularity in the U.S., more than a few American papers have described her as a British version of Music/BritneySpears. However, since she's had more success as an actress than as a singer, Creator/BrieLarson might be a better comparison.
