Justin Bieber Gropes Heidi Klum’s BOOB As They Catch Up At Cannes Party

He was spotted getting rather amorous with Barbara Palvin on Wednesday night.

But on Thursday it was Heidi Klum who was getting the Justin Bieber treatment after the pair ran into each other at a Cannes bash.

And while the 40-year-old supermodel seemed happy to chat to the youngster, she probably wasn’t prepared for his wandering hands.

The cheeky popstar clearly couldn’t resist copping a feel of Heidi’s world famous bod and took the opportunity of a photo to get a bit gropey.

As the good-looking pair were asked to pose together for a piccie at the amfAR gala, Justin decided to get VERY up close and personal with the gorgeous model.

Instead of putting his hand around her waist or shoulder (as is standard photo pose etiquette dontcha know)… he went straight for the boob.

And we have to say, the catwalk star seemed a *little* startled by the whole thing, while Biebs looked like the cat who got the cream.

Perhaps Biebs was feeling a bit more mature than usual thanks to the RETURN OF THE TASH.

The singer’s teeny tiny strip of facial hair has made a re-appearance, and he seemed keen to show it off at the A-list Cannes party.

The evening before, Biebs has been spotted looking rather cosy with former flame Barbara on board a luxury yacht… sparking yet more romance rumours.

Make your mind up, Biebs!
