Beyonce Goes Ass Out For 'Naughty Girl' Performance: 7 Pics

Beyonce rocked a number of sexy costumes during last night’s (June 25) On The Run tour in Miami, Florida but none rivaled the revealing leotard she wore for a sizzling rendition of “Naughty Girl." (Not “Partition” as many sites have reported). At first glance, the diva looked relatively demure in a leather corset before she turned out and showed her perfect ass to 76,000 or so drooling fans.

She then proceeded to work a ballerina’s barre with her fellow dancers — bending and stretching in ways that should come with a warning. Bey positively exuded confidence and sex appeal. We’re used to her pushing the envelope in raunchy clips like the afore-mentioned “Partition” but this is some next-level smut from the queen of R&B! See a selection of semi-NSFW pics up top.
