If anyone can pull off butt cleavage, it's Heidi Klum! Clad in a tiny bikini, the Project Runway host and model flashed her butt while showing her painful sunburn to her Instagram followers on Saturday, July 6, leaving little to the imagination in the NSFW picture.

In the revealing photo, the 40-year-old's backside is seen covered in sand as she pulls down her bikini bottoms to reveal the sunburn, showing a pretty serious tan line. "Ouch!" the America's Got Talent judge captioned the risque snapshot. 

The sunburn was a small setback to what seems to be a picture perfect vacation in the Bahamas for the mother of four (mom to sons Henry, 7, Jonah, 6, and daughters Leni, 9, Lou, 3). On July 5, the star showed just how relaxed she was -- debuting a full head of cornrow hair and referring to herself as a "Bahama Mama." 

The German-born 5 foot 9 beauty recently revealed that she's as low maintenance as they come when speaking about her beauty regimen. 

"I don't like a lot of fuss," the spokeswoman for Clear Scalp & Hair Beauty Therapy explained. "I look like I'm high maintenance, but if you look in my bathroom, I don't have 10,000 products."
