B, you betta work! On the other side of the record, Beyonce’s “Single Ladies (Put a Ring On It)” is earth-shatteringly fierce. The stylish vid focuses entirely on B dancing her ass off with a pair of back-up divas in a routine that looks like it was choreographed by Bob Fosse after a night at the drag show. Ms. Knowles doesn’t quite get it all in one take but she comes remarkably close. To be fair, she probably had way less time than the gaggle of girls and gays who’re memorizing these steps for the clubs as we speak and not of them will be able to pull it off without sweating.
