Country cutie Taylor Swift caught some Miami heat last night when she brought Flo Rida out as a special guest to perform his hit 'Right Round.'

Swift replaced Flo's usual tall blond hook girl, Kesha, who sang on the original track. Swift's semi-interpretative dancing was a sight to behold, and Flo had a huge smile on his face. The duo were clearly having fun, and the crowd ate it up -- the camera work shakes eventually from all the jumping.

This isn't Swift's first hip-hop collaboration. Just last week she did a duet of 'Just a Dream' with Nelly in Houston. In October, Swift and B.o.B performed 'Airplanes,' she collaborated with Usher in Atlanta, and she was reportedly "starstruck" upon meeting and performing with T.I.

Based on her chart success and awards, why aren't these guys starstruck when they meet her?!
