Britney Spears BSPEARSJRROTEM100407_020.JPGMatter of fact, who doesn't crave a little McDonald's once in a while? Our girl Brit and her music producer buddy JR Rotem spent a low-key night at the Viceroy in Santa Monica before heading out for a late night drive... to Mickey's! The twosome made a few quick stops and wound up at McDonald's where Britney got a "number 3 with a coke." One of our photogs even helped out with the drive-thru order!
