Heidi Klum cheekily covers cleavage in racy naked snap to celebrate her 51st birthday

Heidi Klum has shared a scandalous series of naked selfies to commemorate her 51st birthday.

She went topless by her pool as the German-American supermodel spent the special day with her partner Tom Kaulitz.

The America’s Got Talent judge basked in the sun and cheekily covered her cleavage with one hand.

Heidi beamed at the camera and was already dressed for summer with a pair of shades and a baseball cap.

In the background, fans could see her birthday celebrations were in full swing as a bunch of balloons decorated the side of the pool.

Although Heidi has hit middle age, she hasn’t let reaching her fifth decade knock her confidence and still has no problem baring it all on social media.

“I know that I offend people,” she previously told Glamour.

“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.”

Hitting back at her critics, she added: “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.”

Heidi started the celebration by posting a touching black-and-white photo of herself and Tom waking up together.

“Woke up to this beautiful present,” she said in the caption. “I feel lucky and blessed.”

She later posted a shot of the extravagant family meal she had surrounded by her children Leni, 20, Henry, 18, Johan, 17, and Lou, 14, whom she shares with ex-husband Seal.

“All I could wish for,” she added. Another heartwarming snap showed her kissing Tom while they held up their drinks.
