Actress Sarah Jessica Parker has said she is definitely up for a third 'Sex and the City' film.

The 45-year-old, who is currently filming new flick I Don't Know How She Does It, wants to star in another instalment of the film series.

She told the LA Times newspaper: "I would go back. I think there's one more story to tell. I know there is.

"I'd definitely tell that [third] story, and I know Michael Patrick King [the show's writer] would do it right. But maybe not now. Maybe in five years, you know?"

But before she gets involved in another SATC movie, she wants to challenge herself with other projects.

Parker added: "If I'm not scared again that's not good for me.

"That's literally no good for me. If I'm not terrified and nauseous and worried the first two weeks of production, then what's going to happen? You could wither on the vine."

Recently there have been reports that there could be a Sex and the City prequel about a 20-something Carrie arriving in New York, but Parker wasn't sure about that idea.

She added: "I was like, 'Wha-a-a-a-t?'.

"I don't think we can pretend to go back. It's creating two histories.
