Lily AllenLily AllenThink period dramas, and you think Keira Knightley, Emma Thompson...

But Lily Allen? That's an equation we wouldn't have figured.

And yet Lils is set to star in a £2.5m movie based on the classic novel Pride And Prejudice.

Say what?

But fear not, it's a spoof flick.

Miss Allen will be playing Russell Brand's lover, and Stephen Fry will be playing the part of her pops.

What a happy lil' family. (See what we did there?)

Perhaps her new silver-screen role is what has prompted her to shed a few pounds, ditching the curves that set her apart from the norm in skinny old Celebville.

Or perhaps she's been burning off a few calories with her rumoured new boyf, Chemical Brothers star Ed Simons.

Either way she's certainly made some changes, even admitting to Radio 1: "I never wanted to be a role model. That was a label that was thrust upon me.

"I've just lost what I call my hip-tits."

And we agree with Lily that currently there's not a hip-tit in sight.
