She is known as the queen of cool, but Mary J. Blige reportedly channeled her inner-diva during at Clive Davis' annual pre-Grammy bash in Los Angeles Jan. 30, 2010. According to the Daily Mail, Blige yelled at her band in front of a celebrity-filled audience, just before ironically singing her hit song "No Drama." As the band began the song, Blige waved her arms angrily, saying, "Can we get the music right for Mary J. Blige? Are we practicing still?" The audience was reportedly stunned, but the performance was a success.
