8. Wilding Out at Coachella
Date: April 18, 2012
While you were waiting in line for beer at the year's biggest music festival, Rihanna was rolling a blunt on her bodyguard's head. When it comes to pop star divas, it doesn't get anymore gangster than that. On top of that, she smoked impressive amounts of weed backstage with Snoop Dogg and Warren G. We love a girl who knows how to party.
