Kreayshawn may have started off as an internet sensation, but she's quickly proving that she's cultivating a real fan base.

Last night (August 18) at New York City's Highline Ballroom, the Bay Area native rocked in front of a sold out crowd of fans excitedly chanting "Swag!" Hitting the stage around 10:30 p.m., Kreayshawn got things going early with fan-favorite "Rich Whores." Not long after, she brought out her "sister," the controversial V-Nasty. The fellow White Gurl Mob femcee got a chance to shine on her own with a couple solo songs where Kreay played hypewoman. Before long, they switched roles again, as the evening's headliner went into her pseudo-second single "Left Eye" and the older "Bumpin Bumpin"—though V-Nasty never fully played the back.

Fittingly, the 45-minute set began to come to a close with the Sony signee spitting her infectious "Gucci Gucci"—and then running it back and doing it again. The track first went viral online back in May, and is now picking up on both radio and the Billboard charts.

Earlier performers in the night included fellow Bay Area natives Moe Green and Roach Gigz, as well as Harlemite Smoke DZA. DZA is preparing to release his upcoming album Rolling Stoned, which will be made available August 30.
