Ludacris at Sprite Step Off at Roseland last night (video)

The massive crowd at the Sprite Step Off last night got an unexpected treat at the end of the show: hip-hop superstar Ludacris rolled up and did a mini-set that got the ballroom jumping.  Here's a brief video of his opening number.

I've never seen Ludacris live.  He's a consummate performer and knows how to work the crowd.  And when he closed with "Move (Bitch)" the place just blew up.
