Rae Sremmurd may be the youngest MCs to take the stage at the 2014 BET Hip-Hop Awards, but Swae Lee and Slim Jimmy conquered the stage like kings as the night's openers.

Performing their hit 'No Flex Zone' on tonight's telecast (Oct. 14), they made an entrance with big screens, lots of fog and a crew of backup dancers that went hard to the slow-tempo beat. Not only were the performers jumping and dancing around onstage, the crowd of stars was on their feet -- including Lil Mama, who showed her appreciation from her seat.

And if there's anyone who look really proud of the Mississippi rappers, it was EarDrumma Entertainment founder and super producer Mike Will Made It who signed the two rappers.

Rae Sremmurd were bouncing all over the place and set a high energy tone to the show, showing what the future holds for hip-hop.
