Heidi Klum is exposing her private parts to the world this week.
Or at least to two men in particular.
Following an appearance on The Tonight Show in which Jimmy Fallon looked up her skirt, Klum took to Instagram on Thursday and posed with designer Zac Posen.
Topless and wearing nothing but a underwear. If only Posen's hand weren't covering Klum's breasts!!!
"I need something to wear for tonight's @projectrunway @lifetimetv" the German beauty wrote as a caption.
A mother of four, Klum is no stranger to taking her clothes off on the Internet.
Last summer, the model posed in a series of HOT photos on Instagram, one of which showed her hugging a palm tree in just her bikini bottoms and another of which was re-run from 2009 and depicted Heidi Klum nude.
In related news, we really, really, really like Heidi Klum.
She joins a long list of celebrities who have bared their torsos for all to enjoy:
