Heidi Klum Flaunts Major Under Boob in Bikini—See the Funny Pic!

German beauty has been posting extremely revealing pics of herself in bikinis lately

She's outdone herself yet again!

Heidi Klum posted a revealing, and hilarious, pic of herself on Twitter earlier today.

The German beauty flaunted ample under boob while a smiley face was created around her belly button with sand and seashells.

Klum captioned the slightly overexposed photo, "Smile!"

But this isn't the first time that the model has revealed a ton of skin in her twipics. In fact, Klum has made a habit this summer out of showing off her insanely toned bikini bod.

Over Mother's Day weekend, the 40-year-old proudly displayed her washboard abs while floating on a raft in a pool.

Last week she shared possibly her most scandalous photo to date, a pic of her bum in bikini bottoms.

Klum is seen holding a glass of white wine as she works on her summer tan in an orange string bikini.

Then, on the Fourth of July, Klum looked positively white hot in her latest bikini pic on the social media site.

She was snapped taking a dip in the ocean wearing a white bikini, and accessorized for the holiday with an American flag-themed headband and pair of sunglasses.

She also waved two flags as she played in the crystal clear water.

But the skin-flaunting sessions didn't end there…

The America's Got Talent judge posted a snapshot of her sunburned butt while on vacation in the Bahamas and captioned the pic, "Ouch!"

As an added bonus, the Teutonic beauty posted a pic of her in cornrows as she seemingly channeled Bo Derek—all while striking a sexy pose in the ocean against a dramatic sunset. (Anyone else getting a Sports Illustrated swimsuit issue déjà vu here?)

"Thank you for another beautiful day in paradise," she captioned the pic.

If you've got it, flaunt it!
