The 2013 BET Awards were held at the Nokia Theatre in Los Angeles on Sunday and everyone from Chris Brown to Mariah Carey and Stevie Wonder performed.
The event, hosted by funnyman Chris Tucker, opened with a performance by Breezy who displayed his moves to hits like "Fine China," "Don't Think They Know" featuring the late Aaliyah, and "Right By My Side" with a caged Nicki Minaj flying over the crowd.

Host Tucker made his entrance with jokes about taxes and buying too many houses and later attempted his best Michael Jackson performance of "Human Nature."
Aside from Chris and Nicki,  Robin Thicke, Pharrell, T.I., Kendrick Lamar with special guest Erykah Badu, Austin Brown, Mariah Carey, Miguel, Snoop Dogg, Justin Timberlake and more performed.
So who's performance stood out the most?
R. Kelly had the whole crowd singing on their feet when he performed a medley of his greatest hits including"I Believe" and "Bump N' Grind" while donning a jacket with enough spikes to be considered dangerous.

Mariah Carey stunned in a diamond encrusted dress, belting out "#Beautiful" with Miguel. But was the songstress lip syncing?
Twitter wags supposedly thought so, with fans shooting off tweet after tweet dubbing her "a professional lip syncher."
As for the best/most awkward moment? After being announced the winner of Best New Artist, Kendrick Lamar was nowhere to be found to accept the award. However, he resurfaced to perform and later accept his second award Best Male Hip-Hop Artist.
Even more amazing though was Jamie Foxx's suggesting to Kevin Hart that they do a movie together during his acceptance speech for Best Actor. Now that'd be quite the duo!
Did we mention JT also looked more dapper than every while he forced Charlie Wilson, who took home the Lifetime Achievement award, to sing alongside him and Snoop Dogg and Pharrell?
And yes, they really broke it down!
