Funny, but we could've sworn we posted a Beyoncé nipple slip photo before, but a search through the Fleshbot archives revealed merely a (sadly unarchived) near miss and an upskirt shot—which, as all dedicated celebrity skin fans know, aren't the same things at all. Thanks to the reader who spotted this shot on Yahoo! News yesterday, and thanks to Beyoncé for providing us with something else to pore over besides election results this week.
