Photos: Beyonce shows off her booty on stage

Fans who attended Beyonce and Jay Z's Miami concert on Wednesday night must have had the time of their lives. Not only did they watch private home clips of the couple's secret wedding & Beyonce's bare pregnant belly, they also saw Beyonce bare ass. (I'm thinking she probably wore nude stockings)

Beyonce and her dancers wore a costume with the ass cut out when she performed the song "Naughty Girl". See more photos after the cut...
