More on Piper plus Tate

The Sun today continued its in-depth interview with Billie Piper, as featured yesterday.

Piper said that leaving Doctor Who still made her cry but added that she felt it was time to leave lest she got "complacent".

She was quoted as saying: "It was such a hard decision. I still cry about it, I'm such a cry baby.

"I don't know if I'll be able to watch the next series. I'll probably have to sit behind the couch with a cushion over my eyes.

"I just thought it was time to do something new - not because I felt tired, the material was crap or the people were nasty - but just because I felt like doing something else.

"I'd spent nine months filming in Cardiff and that's a long time to be away from your family and friends. I'm a real London girl, I absolutely love it. I found it increasingly hard to be away. I felt like if I'd stayed there any longer I would have become a bit complacent. And, suddenly, you've been doing it for five years and you're too scared to leave."

She said how hard it had been to tell Russell T Davies of her decision, but added that although they were both upset he had supported her completely.

"But life has to move on and there are great things happening in British TV. I just hope I don't regret leaving!"

Discussing David Tennant, Piper calls him "a lovely guy, super-duper down to earth, super-duper smart", and adds: "I think David will be the Doctor for a while, he really loves the show."

Also in The Sun Catherine Tate said she was disappointed she wasn't asked to continue as the Doctor's companion after appearing in the Christmas special.

She was quoted as saying: "They didn't ask me and I tend not to dwell on my failures.

"It was just such a fantastic job to get. It was like making an action movie. It was great but they didn't ask me."

David Tennant is quoted as saying: "An unconventional pairing but we'd have made a great team. I'm very disappointed."
