Kelly Osbourne!!! I know, I was shocked, too!!! Kelly posted her bare derriere to her Instagram with the caption:

 

"It's not a #FullMoon but it feels like one! Good luck everyone tonight! 😜😜😜😜hair my @itsryanrandall"

 

Not saying there's anything wrong with the picture at all, I just wouldn't expect that from Kelly, who usually dresses on the modest side. I guess she was feeling "cheeky"! 

 

What do you think of Kelly's #Belfie??
