Alicia Keys - Alicia Keys And Pitbull Join Los Angeles Jingle Ball Bash
Keys thrilled fans at the Nokia Theatre when she showed up to introduce headliner Justin Bieber, and rapper Pitbull dashed onstage to perform with DJ Afrojack.
Billed stars Ke$ha, fun. and Owl City were big hits and Psy performed his global smash hit Gangnam Style.
But it was Flo Rida who delivered the night's highlight set with a string of high-energy hits, including Low, Whistle and Wild One, which the rapper performed from the shoulders of a burly minder as he carried the hitmaker through the audience.
