Nicki Minaj Denies Lip-Synching At BET Awards

'U could hear me in the auditorium but apparently not in TV land,' she tweets.

Nicki Minaj was one of the biggest winners at Sunday night's BET Awards, taking home Best Female Hip-Hop Artist and Best New Artist and scoring a collective trophy with Young Money for Best Group.

The saucy upstart has made a name for herself with her rollicking flow, but fans were buzzing about what they thought didn't come out of her mouth at the show, accusing the rap diva of lip-synching through her performances.

Minaj took to Twitter on Monday (June 28) to dispel rumors that she didn't bring all her skills to the stage.

"U could hear me in the auditorium but apparently not in TV land," she tweeted. The star also added that technical difficulties were at play. "Shout out to the sound guy."

However, the "Massive Attack" rapper assured fans that the sound issues will be cleared up when the network rebroadcasts the show. "They say it'll b fixed wen it re-airs. :/"

Overall, it was a busy night for Minaj. After winning Best Female Hip-Hop Artist (a trophy she scored solely on the strength of her mixtapes and work with Young Money, since the star has not yet dropped a major-label debut) and calling for "positive energy" among women in hip-hop, the MC popped up in two different performances. She emerged from a cloud of smoke in a skintight catsuit and spit her rapid-fire verse for the remix of "Hello, Good Morning" during Diddy-Dirty Money's performance. She also helped close out the show, performing her collabo with Ludacris, "My Chick Bad," with Mötley Crüe's Tommy Lee on drums and taking the stage again minutes later to rock DJ Khaled's posse cut "All I Do Is Win."
