What do you do after a tough breakup?
If you're Kelly Osbourne, and you just split from fiance Matthew Mosshart, you go tag some walls with graffiti... alongside Justin Bieber!
That's what went down last night between the singer and the fashion guru, as Osbourne posted a couple photos to Instagram of her and the Biebs spray painting away.
"Just had so much fun getting lessons from @justinbieber on how to #SprayPaint! Needless to say I was s*** all I did was the horns!" Kelly wrote as a caption. "Justin is a lovely boy and have turned me into a true #Belieber tonight!"
