Heidi Klum poses topless in itty-bitty bikini bottom: ‘My hot girl summer’

For Heidi Klum, bikini tops are totally optional.

The supermodel, 49, shared a cheeky Instagram photo over the weekend, posing in a string-tied white bikini bottom and absolutely nothing else, with her blond waves cascading over one shoulder.

“My hot girl summer 2022,” Klum captioned the shot.

The “America’s Got Talent” judge posted a similar topless pic in mid-July, ditching half of her skimpy red swimsuit and joking, “Boy it’s H☀️T.”

And just last week, she took it all off for a sexy black-and-white snap in bed captioned, “Come back to bed Baby ❤️.”

Her husband, Tom Kaulitz, seems to be a fan of summering in the buff as well, with Klum recently snapping a stealthy pic of her spouse with just a towel covering his crotch.

It would appear the German American catwalker didn’t burn all her bikini tops, however; on Monday, she shared an Instagram Reel of herself lounging beneath a palm tree in both halves of a pink-and-orange ombré two-piece.

It’s no surprise Klum would be sticking to swimwear during the dog days of summer — although as she recently revealed on “The Late Show With Stephen Colbert,” she’s able to stop her face from breaking a sweat.

“I just tell myself not to sweat in the face!” she said. “That’s my talent. It’s hidden, because I don’t show it.”
