Heidi Klum says Justin 'Boober' didn't grope her

Supermodel Heidi Klum has spoken out in Justin Bieber's defence after the pop star was snapped appearing to grope her breast during a photo opportunity at a recent charity gala in Cannes, France.

The German beauty met Bieber during the amfAR benefit on Thursday, May 22, and agreed to pose for pictures with the songwriter.

But the images merely added to Bieber's bad-press woes because in them, the 20-year-old's palm seemed to be touching the side of Klum's boob in her strapless blue gown.

However Klum has now cleared up the claims, insisting Bieber was nothing but a gentleman.

"He was totally not touching me, by the way," she told the New York Post's Page Six column.

"I know that was like a big thing, 'Justin Boober'. It maybe looks like that because sometimes in pictures things look a little... (suspect).

"I'm like, 'What are they talking about?' He's very polite and very nice."
