Britney Spears, her no longer estranged mom Lynne and sketchball manager Sam Lufti hit a Beverly Hills Mercedes-Benz dealership earlier this afternoon in search of some good old-fashioned retail therapy. Brit Brit arrived on the scene dressed in typical scattershot fashion: faux intellectual glasses, the dirtiest pair of cowboy boots west of El Paso and some sort of belly-baring lace-accented sweater thingie. And in case you're wondering, no, she didn't buy anything. Good thing, considering she still doesn't have a valid driver's license. [TMZ]
