Justin Bieber + Friends: Kesha
This seems like one of the least likely pairings imaginable: the dirty, oft-drunk pop tartlet that is Kesha and the squeaky clean, coming of age Canadian that is Justin Bieber. It's like mixing Jack Daniel's and Tim Horton's!
However, the two are pals, however shocking that may be. They're even planning a duet! File that under tracks we absolutely can't wait to hear.
