Heidi Klum Reveals Bare Butt In A Racy 'Naughty Spoon' Instagram Photo (NSFW)

Looks like Heidi Klum has been a little bit naughty!

The 42-year-old supermodel took to Instagram on Sunday to share a very racy snap, showing what appears to be a man lifting up a woman's denim skirt (which we presume is Heidi's), revealing her bare butt. His other hand holds a wooden "naughty spoon" which he presses against the mother-of-four's derriere. Klum simply captioned the photo "Ouch."

Though she's no stranger to sharing bikini snaps on Instagram, this is the first time the blond beauty has shared a risque picture of herself via her social media accounts.

Watch the video above to see the cheeky snap!
