Who's The Yum Mum?

Guess who this is?Two kids. Two kids.

That's how many children this celeb has had and yet she's still got a belly flatter than a freshly tarmacked road.

It's enough to make us regret that Saturday night takeaway. And the Sunday one, too...

But luckily for us, we don't have to slip ourselves into swimwear for photo shoots with Harper's Bazaar magazine.

We'd probably need about two year's notice to prepare ourselves.

So, we'll leave all the hard work to this famous mum.

And you can find out who she is in the gallery above.
