The punk rock fashionista, 29, shared — and bared — her backside in a racy thong photo posted to Instagram.
“It’s not a #FullMoon but it feels like one!” Osbourne captioned the photo.
In the odd snapshot, the “Fashion Police” star poses against a wall, with hairstylist Ryan Randall apparently admiring her pert derriere while holding a bouquet of flowers.
A scantily clad Osbourne wears a black crop top in the pic and has her jeans around her knees while also showing off her worn white socks.
“Good luck everyone tonight! hair my @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?
