BSPEARSRALPH091207_01.jpgBritney Spears BSPEARSRALPH091207_16.jpgWe couldn't have been happier to see Britney break out a big smile (her first since the VMAs) yesterday afternoon when we spotted the pop princess picking up a few essentials at Ralph's. Her constant companion Alli, however, was a little less copasetic - especially when the subject of Sarah Silverman came up! The contentious host's name had barely crossed our videographer's lips before Alli snarled back that Sarah was "mean", and that one day she'd have children of her own. Ouch!

Edit: For your convenience, we went back and subtitled Alli's exchange with our camerawoman - hopefully that helps further your understanding of the situation.
