Does Heidi Klum have some aversion to clothing? The "Project Runway" host has posted yet another topless photo on her Instagram account, just a few days after posting her braless picture and another that features her butt's close-up.

It's clear that Heidi has been enjoying her vacation in Bora-Bora. She has been documenting her beach holiday on her social networking accounts, from seemingly mundane shots (pictures of her red pedicure and her Bahama braids) to more risqué photos (photos of her uncovered body parts).

"Last day in paradise, love Bora Bora!!" Heidi captioned her latest picture, in which she is seen hugging a palm tree in nothing but just a bikini bottom.

On July 16, she also posted another picture featuring a smiley on her flat belly and her hand doing a poor job at covering her full and bare boobs.

Ten days prior to that, she had gone a different direction and exposed her near-naked bum on Instagram.

"Ouch!" the mother of four wrote, pointing to her sunburnt butt.

By now, we should all be used to a naked Heidi, but the German supermodel has such a sexy body that it's hard not to look again and again each time she posts nude photos.

But since it was her last day on the beach, it might take a while before she posts another one. So to help us remember how she spent her vacation, here's a slideshow of the sexiest photos Heidi posted for the month of July, plus a few beach shots way from way back then.
