The 38-year-old actress - who previously played the part of Rose Tyler in sci-fi series - has ruled out a return to the show, but she has recommended the 54-year-old star as the next Doctor.

Speaking about a possible comeback for Rose, Billie said: "It’s the face of a family show and that’s a lot of responsibility that I’m not comfortable with."

Billie previously starred alongside Christopher Eccleston and David Tennant on the BBC show.

And the singer-turned-actress thinks Helena is the perfect candidate to replace Jodie Whittaker as the Doctor.

She told Total Film magazine: "I know who … Helena Bonham Carter.

"She’s got that madcap energy - she’s a ruddy powerhouse."

Billie previously revealed she didn't want to return to 'Doctor Who' because she found it to be too time-consuming.

The actress - who rose to fame as a teenage pop star - hates the idea of spending time away from her kids.

Billie - who has Eugene, nine, and Winston, 12, with ex-husband Laurence Fox, and Tallulah, two, with Johnny Lloyd - explained: "I wouldn't go back. It’s a great role, but you're away from your kids for so long. My experience was that you were in Wales for nine months solid.

"And as a job it dominates your life. It's mainstream family viewing so you can't really escape it. It feels like it makes you very, very famous."

Billie also revealed that her kids aren't interested in 'Doctor Who' either.

She said: "They certainly don't give a s*** about my music career. They don't like seeing me in 'Doctor Who', and I have pushed that on them a number of times.

"My elder son would get very upset that I was being chased or scared or attacked, so I thought, 'OK, this is a weird mental leap for you.' "
