Kate Hudson shows off her post-baby body for the first time since giving birth - and she looks AMAZING!

It's only been five weeks since Kate Hudson gave birth to her first baby with boyfriend, Danny Fujikawa.

But the 39-year-old is already showing off a slim post-baby figure.

The 'How To Lose A Guy In 10 Days' star - who welcomed a little girl called Rani into the world - made her post-baby debut with Michael Kors at UCLA to honour her new ambassadorship to the United Nations Food Programme.

The blonde beauty showed off her slim waist in a black sequin dress with a black belt and wore the low neckline to flatter her figure.

Fans have been left stunned over her flat stomach, with many saying it doesn't even look like she had a baby.

Kate is also mum to Bingham, 7, with Matt Bellamy, 40, and Ryder, 14, with Chris Robinson, 51.

We think she looks amazing!
