Heidi Klum gets naked in a recent Instagram photo that benefits AIDS research - Heidi Klum looks great at 40-years-old! Seal's ex-wife previously admitted that she feels "free" when nude. Check out the supermodel's Instagram photo here!

Heidi Klum posed nude to promote AmfAR's new tote bag, designed by Jean Paul Gaultier. The naked supermodel covers her assets with the strategically-placed blue-and-red canvas tote. All proceeds from the bag will go toward AIDS awareness and research, the Huffington Post reports.

The special edition bag goes on sale June 1 at Bloomingdale's. The bag is $35, the Daily Mail reports.

Heidi Klum posted the photo on Instagram with the caption: "Loving my new #amfARTote by #JeanPaulGaultier. In-stores @bloomingdales June 1. All proceeds go to@amfar #AIDS research!"

Her porcelain skin, blonde bangs, and red lipstick remind us of Taylor Swift - except Heidi Klum is almost 20 years her senior!

But the 'America's Got Talent' judge insists she isn't "ageless" and can notice a difference in her body and looks.

According to TNT Magazine, Heidi Klum said: "If you put me a 20 year old next to me, of course you see a difference, but that's normal. I'm not trying to be like, 'I'm 20!' Because I'm not."

In an interview in Us Weekly magazine, the German supermodel admitted that she enjoys being naked.

"People laugh when I say this, but I grew up going to nude beaches with my parents. It was very free. I took my top off, and I still do. I don't like to have tan lines on my boobs."

A quick skim through Heidi Klum's Instagram photos shows just how much she likes to be "free"; bikini beach snaps show off ample cleavage and her infamous butt crack. This woman isn't afraid to show off her gorgeous skin - and we don't blame her. If we look like Heidi when we're 40, our Instagram photos will be NSFW.
