Billie Piper is writing a rom-com

Speaking to the Guardian newspaper, she explained: "If I watch 1990s romcoms now, I find them hard to understand. They just sit differently.

"Even though I love those movies, it's a time that felt so radically different from the world we live in now. So I'm trying to do something that feels authentic to now, but still feels dreamy and hopeful."

When asked how she deals with writer's block, she replied: "I panic! Luckily, I'm so green even the bad days seem achievable."

Billie went on to add: "I don't just want to be an actor for hire any more. It feels too frightening. But then, you know, what am I going into?

"Writing things that also may never get made? People want to make massive things for loads of money, and then the expectation is that those numbers reflect that spend, and if they don't then they're gone. It's really sad."

It comes after Billie admitted she struggles to find a work-life balance when juggling her acting career with raising her three children - Winston, 15 and 11-year-old Eugene with ex-husband Laurence Fox and five-year-old daughter Tallullah with former partner Johnny Lloyd.

She told Independent.co.uk: "Working mothers' stuff is really complex."

Asked if she has a work-life balance, she added: "No. I don't. I feel like we've been told we should have that. But there's absolutely no way I have that?

"And that's one of the tiring things about being an actor for hire - if you're working in a lead role, you're out of the house sometimes 15 hours a day.

"I really struggle with that now I've got three kids."

Billie explained it can be particularly difficult as she may have an intense three-month period of filming and then no work for the rest of the year.

She noted: "But when you're gone, you're gone. Those extremes make for something quite rocky."
