Britney Storms Out On Kevin After Argument At Pre-Grammy Party

Not only is Britney Spears dealing with the uproar over her driving with baby son Sean Preston in her lap, Star magazine reports that the singer and her husband Kevin Federline got into a shouting match at Monday night’s Rolling Stone/Verizon-sponsored pre-Grammy party at the hot nightclub Avalon, where Kanye West performed. “It was shortly after midnight and Kanye had only been on stage a few minutes when Kevin and Britney got into some big disagreement which turned into a full-scale shouting match,” a witness revealed. “They both looked pretty angry and everyone else in the box was staring at them with amazement and shock. After a few minutes of yelling at each other, she stormed out leaving him in the box. She left with one of her bodyguards, got in her car and took off. Kevin stayed in the box with singer Brandy and his buddies, drinking the Sky Vodka that was being promoted at the club last night. He stayed till the end of the show.”
