There's more to Heidi Klum's racy photographs than meets the eye -- as it turns out, the former Victoria's Secret supermodel recently revealed to Access Hollywood, the skilled photographer behind her risque snaps is none other than her own mother.

"You will be surprised when you hear that my mom takes most of the photos," she told Access Hollywood of her recent string of sultry bikini shots. "Yeah, my mom and dad. They were on holiday. Yes, so my mom can take some good photos."

Klum, 40, recently had fans all atwitter after posting a NSFW picture of her pulling down her bikini bottoms to reveal her sunburned, sandy bum for all to see. "Ouch!" the America's Got Talent judge captioned the shot over the Fourth of July weekend.

A few weeks later, Klum was at it again, posting a shot of herself topless and clinging to a palm tree in scenic Bora Bora.

"Last day in paradise," she shared. But despite all the Internet hoopla, the mother-of-four sees nothing wrong with daring to bare her assets in public.

"I'm European. I don't like wearing tops," she explained to Access Hollywood. "And I don't like tan lines."

It seems like the apple doesn't fall far from the tree. Klum's parents are similarly free-spirited, she said in a 2010 interview with Taller magazine.

"My parents are still naked," she said at the time. "I mean, it's not like we're hippies and we run around naked, but if they happened to be in their room changing or something or someone comes out of the shower, they're not, like, 'Oh my God. No. Close the door.'"
