Heidi Klum reveals more than she bargained for as she suffers wardrobe malfunction in Cannes

HEIDI Klum accidentally revealed her pants as she posed in a very extravagant frock.

The supermodel, 49, once again pulled out all the stops at Cannes Film Festival in the plunging dress with thigh high split.

The stunning gown also features metres of pastel green tulle, creating a train and very dramatic look as she walked.

Aside from a brief flash of her nude underwear, Heidi managed to keep her modesty intact as she posed away.

Heidi has been enjoying the festival this week alongside her Tom Kaulitz, 33.

She previously wowed in a dramatic yellow gown, which featured wing like detail.

The German-American star, a panellist on America’s Got Talent, recently told how she has no desire to slow down as she approaches 50 and is still happy with her body.

She told Closer: “I’ve always felt great about my body. I’ve always been very confident, and I still am.

“[But] I wouldn’t go to the gym in a sports bra and little shorts – I feel like everything’s jiggling around.

“The metabolism definitely changes when you turn 40. I always thought, that’s not going to happen to me, but it is happening to me. If I indulge more, I have to exercise more.”

Last year Heidi even expressed a , her first with musician Tom.

She said: “I mean wanting it and it actually being possible are always two different things. The big 50 is just around the corner. And things get harder when you get older.

“But would I want it? Sometimes I think yes.”
