Five weeks after she popped out child number four, the German supermodel was back on the catwalk in New York on Thursday night.

How does she do it?

Heidi claims she dropped the baby weight naturally, insisting, “I didn’t do too much, I have to tell you. I do eat very healthy and I drink lots of water and I breastfeed and I’m just very active.”

But we don’t believe her.

Either’s she’s carrying her children in a removable womb, there’s some kid of surgery involved — or she’s an alien.

There could have been a whole lot more Paris Hilton…

The socialite’s mum Kathy has revealed Paris signed up for breast enlargement surgery to inflate her famously flat chest — but backed out at the last minute.

Kathy says: “At one point she was like ‘I wanna do this and that, I’m so flat!’ but then all of a sudden she was like ‘I love it. I don’t care. I love it.’ I’m proud of that; I think that’s really nice.”

Who’d have guessed these two shared clothes?

What’s impressive is that Rihanna rocked the sweater dress at dinner in LA on Wednesday night — and then sent it on a transAtlantic flight to London, so Katy could slip it on for a night out in the British capital!

… Unless it’s not one-of-a-kind

We prefer our theory.

We all wondered where Heidi Klum had gone after giving birth to her fourth baby last months – it seems she locked herself away in a gymn!

Just look at her – just four weeks after giving birth Heidi’s svelte, supermodel figure is back, and she looks incredible!

She must have worked out non-stop!

Never mind Victoria’s Secret, what’s Heidi’s?

Christina Ricci caught our eye at a party in New York last night.

Love obviously agrees with the actress, who was looking very glam dressed in Alexander McQueen.

Ricci has been dating photographer Curtis Buchanan for the last three months and arrived in the Big Apple fresh from a vacation in Florida sun with her beau.
