Kelly Osbourne, Erm, Shows Off Her Bottom On Instagram

Kelly Osbourne has been showing off her smalls on Instagram - and, well, if we had bottom that looked this, we might well do the very same thing.

The image shows Kel in a tiny pair of pink lace knickers, meaning she's now joined the 'belfie' brigade. She uploaded the pic to Instagram and wrote: "It's not a #FullMoon but it feels like one! Good luck everyone tonight!"

According to the Mirror, her friend Ryan, also pictured in the shot, uploaded the pic, too and wrote: "Aren't these flowers amazing!? @kellyosbourne and I BEHIND the scenes."

The pair were getting ready for a night out at the 4th Annual 24 Hours Plays in Santa Monica, California.


Kelly looked fabulous at the bash in a piano key-print dress, and worked punk-rock hair with shaved sides and plaits enhanced with safety pins.

She also shared pics on Instagram of her night out, writing: "I had so much fun dancing the night away with #Alanis @morissette at the after party for @24hourplays! This dance is called #TheBeard."

She also revealed a recent close-up of the 'safety-pin updo', captioning: "#obsessed with my hair tonight!"

She definitely looks cool, but we think you may have to be a bonefide child of rock royalty to pull this one off.
