Heidi Klum, 50, stuns as she goes braless in very daring cut-out dress as she hits the red carpet in Cannes

HEIDI Klum looked a million dollars as she arrived at a glamorous charity gala in Cannes wearing a very daring white dress.

The plunging fishtail frock, with its bejewelled detailing, showed plenty of cleavage as Heidi graced the blue carpet for the the Knights of Charity gala at the 77th edition of the world famous film festival.

The 50-year-old German model and TV star beamed brightly for the cameras as she tucked her flowing blonde hair behind her ears.

Held at the Le Palm Beach, the gala's exclusive auction prizes included a private tour of UNESCO world heritage sites with Duchess of York Sarah Ferguson, a game of paddle ball with Eva Longoria and a day on set with actor Andy Garcia.

There were performances from Robin Thicke and DJ Blond:ish and the after party was put together by LA nightlife kingpin Darren Dzienciol, featuring music from DJ Mr. Bones.

Heidi is staying at the five-star Hotel du Cap-Eden-Roc in Antibes, a favoured spot for A-list celebrities.

She gave her followers insight into her first hours in the South of France, writing on Instagram: “And who’s the first one with a towel down, jet-lagged, ready to get a tan with no one in sight? Moi!” 

This morning she was back outdoors, relaxing on a lounger in more low-key attire with a cuppa.

The beauty, who judges on both America's Got Talent and Germany's Next Top Model, has spent more than three decades in the limelight.

Whether its due to her modelling and TV work, her relationship with toyboy musician husband Tom Kaulitz, 34, or her unbeatable Halloween transformations, Heidi gets people talking.

She's not afraid to have an opinion, and in an interview with earlier this year, she defended her forthright attitude.

"I know that I offend people," she said. "But I think you have to remain authentic. I'm a woman who likes to be feminine, who is sometimes loud and colourful. And there are women who aren't like that.

"If I annoy people with it, all they have to do is unfollow me. It's just a small push of a button. Everyone should be who they are and who they want to be. I don't pretend I'm different just because this or that person might not like me the way I am."

And when it comes to criticism of the 16-year-old age gap between her and husband Tom, Heidi think it's nothing more than old fashioned sour grapes.

"I think it's often just spitefulness," she said. "Perhaps many people also think I've had too much luck in life. I have a great job, I get to travel the world, I can buy expensive things. And now I've also got myself such a great man. Maybe people don't begrudge me that.

"Nowadays, people are rightly extremely careful about everything they say – except age shaming. People continue to criticise [in that respect]."
