Heidi Klum's latest Instagram pic seemed to suggest that she might have an "S&M" side after showing her pert butt cheeks in a provocatively hot NSFW snap taken by a man. In the photo, the 42-year-old German supermodel was seen being spanked with "the naughty spoon," maybe by her current beau Vito Schnabel, Daily Mail noted.

So, is Heidi Klum an Anastasia Steele's wannabe who likes to be dominated? In the racy photo she shared on Instagram, the mom-of-four appeared to like a little "Fifty Shades"-like spanking courtesy maybe of her 29-year-old boyfriend Vito Schnabel. However, risqué social media posts from Klum aren't surprising anymore because she is often photographed either in a very passionate display of affection with her lover or in NSFW poses sans clothes.

"[I feel sexiest] when I'm shooting, to be honest, the less I have on," Klum said in November, as per Us Weekly. "Many people maybe are the opposite, like maybe they [prefer to be] more dressed. But the less clothes I have on, the easier it is for me to shoot, and the sexier I feel."

The act of domination in Heidi Klum's Instagram post on Sunday was only captioned with the word "Ouch," E! News noted. While she is occasionally seen in her bikini or lingerie since she has her own branded intimates line, her latest post showed Klum's naughty and wicked side.
