Diplo has been known to surround himself with barely clothed women at the Wynn hotel when not dating Katy Perry or M.I.A. (He and M.I.A. made "Paper Planes," and his August remix of her "Bird Song" is sublime). Diplo was put on this Earth to collaborate. He and Skrillex gave Justin Bieber "Where are U Now?" Although his real masterpiece, with DJ collective Major Lazer, is "Bubble Butt." "Bubble Butt" by any other name would sound just as sweet.
