Billie Piper has admitted that she has no plans to pursue her acting career in Hollywood – at least not for the time being.

The former Dr Who star has said that she had pondered the idea of going Stateside, but has postponed it for now because of her two-year-old son Winston.

“I keep thinking about it, but then I like England,” she said.

“To be out there with a baby and to do seven, eight auditions a day is just not massively appealing at the moment.”

The 28-year-old returns to screens this week in of Secret Diary Of A Call Girl – but has said the new series of the show will be the last one.

“I think we’ve pretty much been everywhere with the stories and as that’s at the heart of every episode, you wouldn’t want to exhaust it to the point of just complete ridiculousness and seediness,” Billie explained.

“I really like this job but you always want the story to have legs and not be that you’re scraping the bottom of the barrel. I think if we go any further then we might be guilty of that.”

However she added she was looking forward to working on some new projects.

“I just want to do something radically different and I don’t know what that is yet. I think I’ve just chosen things that have interested me and then kept trying new and different things,” she said.

“It has worked out well and I can thank Doctor Who for all of that really. It was wholly responsible for giving me a great opportunity.”
