Cast
Billie Piper

Billie Piper achieved her first claim to fame when she was chosen to appear on the Saturday morning kids' show Scratchy & Co, but at the age of 15, she became a household name after was offered her very own record deal. In 1998, with the release of her debut single, Because We Want To, she became the youngest artist to ever debut at a number one single. With a string of both successful and unsuccessful records behind her, Billie decided to end her music career for good in 2003, returning to her original ambition of acting.

While living in LA, she took up drama lessons, and soon managed to earn roles in the BBC's The Canterbury Tales and the one-off drama Bella and the Boys. She was a hit with audiences and critics alike, and it wasn't long until she was labelled one of Britain's brightest youngest talents by the press.

In 2004, after auditioning for the role, she was cast as Rose Tyler in the BBC's revived series of Doctor Who, and it was her portrayal of the Doctor's fiesty companion that stole the heart of the nation, and audiences watched and wept in their millions when she decided to bow out of the show in July 2006.

After leaving Doctor Who, she released her own autobiography, Growing Pains, and also made her West End debut in Treats. In addition, she appeared in several one-off dramas for both the BBC and ITV, including The Ruby in the Smoke and Mansfield Park.

In 2008, Billie returned to Doctor Who for three episodes in its fourth series, a comeback that had always been planned since she had left. She also reprised the character for a small cameo appearance in the 2010 New Year's Day special, The End of Time, Part Two.
