LOS ANGELES -- While the rest of us have to wait until Sunday night to see [article id="1647602"]VMA nominees Florence and the Machine[/article] re-create the chaotic beauty of their "Dog Days Are Over" video on the stage, the crowd at Perez Hilton's One Night in Los Angeles bash at the Wiltern Theater on Saturday night got a special taste of the U.K. group's spellbinding live set.

Leading lady Florence Welch, decked out in a simple lingerie-inspired dress, kicked off the party with her tracks "Drumming Song" and "Kiss With a Fist." Accompanied by a guitarist and harpist, she played to a packed house, which included celeb guests like "The Hills" star Lo Bosworth. In the short, three-song acoustic set (presumably to conserve [article id="1647577"]energy for the VMAs[/article]), Welch rocked the house with her powerhouse voice. "Thanks again," she told the crowd before belting out her [article id="1647375"]VMA-nominated track, "Dog Days Are Over."[/article]

After Florence left the stage, Perez Hilton came out to thank the crowd for coming. Performances by "Dynamite" singer Taio Cruz and Pitbull followed. Producer Kevin Rudolf, Dr. Hollywood and Skeet Skeet all served time in the DJ booth, and N.E.R.D. closed the night out with a loud, raucous set including fan favorites like "Drop It Like It's Hot."

Perez later tweeted, "L.A. showed so much love tonight! It was SUCH a special evening! #OneNightInLosAngeles."
