The Enquirer reports that Britney Spears had a jealous spat with fiance Kevin Federline while shopping at Fred Segal on Melrose Avenue. Britney was trying on some clothes, and spotted Kevin chatting with a sexy saleswoman. "What's the matter with you!", Britney yelled at Kevin, yanking him away from the saleswoman. Kevin pleaded, "I wasn't flirting - I was just talking with her!" But Britney had none of it, dragging him into the changing booth screaming at Kevin, then storming out of the place first throwing the dress she had tried on at the salesgal with Kevin meekly following her out.
