Lily Allen to star with Dr Who Matt Smith?

Lily Allen could be appearing as 'Dr Who''s new sidekick, people behind the show have revealed.

The BBC are looking for a girl to join the new Doctor Matt Smith when he takes over from David Tennant in 2010, reports The Daily Telegraph.

Executive producer of the show, Piers Wenger, told the paper: "Having got the casting of the Doctor out of the way, the companion role is where we will be looking next. Someone terribly exciting like Billie Piper, who was at the beginning of her acting career but who had a profile for other reasons, would be great. We are looking for someone whose light can burn brightly."

Sources say that other female celebrities being considered include Kelly Brook and Rachel Stevens.

Wenger added: "We would never cast anyone on the basis of their celebrity, but if Lily wanted to audition we would be delighted. It would be a lot of fun."
