Rihanna hung out at the Coachella Music Festival this past week with her BFF Katy Perry and shared a picture of herself sitting on top of a man's shoulders scooping mystery white flakes into a hollowed-out cigar.
Accompanied next to the picture was a quote that read: 'Memories don't live like people do #coachella'.
Ri is no stranger to showcasing her freewheeling lifestyle on social networking sites. On Monday, she shared over 100 photos of herself vacationing in Hawaii, some of her topless underneath a waterfall.
Perhaps in defense of her increasingly risky behavior she Tweeted yesterday: "I'm crazy, and I don't pretend to be anything else."
Meanwhile, some fans responded with worry and caution.
"What is that white matter? Riri I hope is not cocaine..the substance is cocaine, please do not use it ever again!" said one fan.
While others seemed to take it less seriously.
"Tortilla chips + feta cheese. Hommie got hungry."
