Rihanna Sips From a Flask During the Grammys, Continues to Be a Legend Among Us

Rihanna has an amazing habit of taking wine glasses from restaurants and walking down the street with them because, well, she's Rihanna. But at the Grammys on Sunday, the "Work" singer was spotted seated in the crowd sipping from a diamond-encrusted flask, proving that she's not only a total badass, but also someone who has her priorities straight. Never change, Rihanna.
