Sometimes you find friends in the most unlikely places, which may explain the strangest graffiti duo ever—Justin Bieber and Kelly Osbourne. Last night the two celebrities got together to spray paint a wall. How can this not be a publicity stunt? 

Most #Random but fun night with @justinbieber!

— Kelly Osbourne (@KellyOsbourne) January 9, 2014

Osbourne posted an image on Instagram of her and the Biebs spray painting with the caption, "Just had so much fun getting lessons from @justinbieber on how to #SprayPaint! Needless to say I was shit all I did was the horns! Justin is a lovely boy and have turned me into a true #Belieber tonight!" Because obviously Justin Bieber is qualified to give street art lessons.

A least this spray painting venture seems like wholesome fun, a change from Bieber's recent extracurricular activities. In Brazil, Bieber was charged with vandalism for tagging a wall (along with a more notorious scandal in the country), and supposedly he sparked a graffiti revolution in Colombia. 

Bieber and Osbourne put up cartoonish characters including an animated light bulb that may be inspired by Meres One's 5 Pointz tribute on Rag & Bone. At least Bieber steered clear of racist monkeys this time.
