With the role of Rose Tyler, Billie Piper has come of age as an actress.

A former twice UK Top 40 singles chart Number One singer, Piper is stunningly garrulous, fun-loving and brave as the Ninth Doctor's first travelling companion. Abandoning a dull life as a department store sales assistant and a relationship with a predictable boyfriend (Mickey), Rose Tyler is a far more self-reliable DOCTOR WHO companion.

A true heroine for a new generation of children to admire.

Julie Gardner, Head of Drama for BBC Wales, said she needed to find a "unique, dynamic partner for Christopher Eccleston". She said the actress "fits the bill perfectly".

"Billie is beautiful, funny and intelligent.

Born on 22 September 1982.

What has Piper said about her supporting role in DOCTOR WHO?

"DOCTOR WHO is an iconic show and I am absolutely thrilled to be playing the part of Rose Tyler."

"I am also looking forward to working with Christopher Eccleston and writer Russell T Davies."

"Rose is a feisty character, she's got balls."

"I was very similar at 19. I wanted something to happen in life, I wanted a bit more. I wanted to find someone who could challenge my ideas. So I definitely tapped into that."

She continues to star in DOCTOR WHO for NEW SERIES 2.
