Brazilian supermodel Gisele Bundchen was left shocked and scared when she confronted an obsessed fan who had her image tattooed on his chest.

The stunner was working a fashion show in Brazil last year (04) when the superfan ran up to her, sobbing and baring his chest.

She recalls, "I had a bunch of security guards around me and when I was leaving this guy just took off his shirt and he was crying, he was a bit crazy, for sure.

"He was like, 'Look, I love you,' and he had me tattooed, like, my whole body on half of his chest.

"I was like, 'What is that?' I wasn't stopping to pay attention to it because I thought he was maybe a psycho or something... I got really scared."

Bundchen still can't believe her fan went to such great lengths to show his devotion: "What if he doesn't like me tomorrow... and he's got my whole body tattooed forever."
