Britney Spears back!

Brit stopped by McDonald’s this morning around 9 a.m. on her way to one last rehearsal before her music video shoot for Womanizer! Queen B fueled up on a hash brown (loves it!) before heading to downtown LA, to an interior set for the first scene of the video. We saw Britney in a brunette wig, which we believe she’ll be wearing in the video … And now she’s doing a night shoot in a tunnel downtown — lights, camera, action, y’all!!!!! This custom convertible Cadillac Escalade was parked on a tow truck outside the first video location — cute!
