Mariah Carey, you may be a certified diva but being late to an award show is a HUGE no-no! The songstress was set to unveil her newest album, 'Me. I Am Mariah… The Elusive Chanteuse' before the World Music Awards in Monte Carlo. But for some unknown reason, the event was pushed 4 hours, causing a four-hour delay, making Miley Cyrus , Leona Lewis , and Tinie Tempah adjust their schedules to accommodate the delay.
