Not buts about it: Kelly Osbourne is looking hotter than ever. The TV personality showed off her backside this weekend, and you might just be shocked by how toned it is!

On June 20, Kelly posted a rather racy photo (at left) of herself with her pants pulled down. Her butt is exposed, and her panties are revealed. 

"It's not a #FullMoon but it feels like one!" she cheekily captions the photo. "Good luck everyone tonight! hair by @itsryanrandall." She finishes the caption by giving a shout-out to hair stylist Ryan Randall.

We're not sure what exactly inspired Kelly to pose for this pic, but as the saying goes: If you've got it, flaunt it post it on Instagram. Or perhaps she's just busy straightening out that floral painting? 

This isn't the only recent Instagram photo of Kelly's that is surprisingly sexy. She posted one photo on June 22 in which a doll of 90210 character Dylan McKay is poking out of the front of her shirt. 

Kelly, who called off her engagement to Matthew Mosshart in January 2014, has been busy lately, as she appears in next month's TV film Sharknado 2 and was in Pharrell Williams's music video for "Happy."

What do you think of Kelly's sexy pic?
