Nicki Minaj is in legal trouble over her alleged diva antics. The 'Anaconda' rapper has been slapped with a $50,000 lawsuit for showing up late for an NBA All-Star event in 2011, and leaving early.

According to the New York Daily News, IMP Entertainment claims that Minaj agreed to perform at an event for an hour but showed up 90 minutes late and only performed for 30 minutes.

In a suit filed on Aug. 13 in Manhattan Supreme Court, the entertainment company claims that Minaj was paid $53,050 to cover her fees and expenses prior to the Feb. 19, 2011 show. IMP Entertainment feels that the Young Money rapper "defeated the entire purpose of the agreement" and they want their money back and other unspecified damages.

Reps for Minaj have yet to respond to the accusations in the lawsuit.
