Rihanna doesn't mess around.
After MTV tweeted a link to a story about how her "marijuana photos from Coachella sparked controversy," the 24-year-old singer took only 12 minutes to respond via the social networking site.
Whether she cares or not, Rihanna's fans were surprised to see her upload Instagram photos that feature her sitting on top of a bald bodyguard's head, rolling what appears to be a cigar leaf full of marijuana.
Last October, Rihanna admitted she struggles with being in the public eye. "People -- especially white people -- they want me to be a role model just because of the life I lead," she told British Vogue. "The things I say in my songs, they expect it of me and [being a role model] became more of my job than I wanted it to be."
