Britney Hits The Roof At Movie Premiere

Pop Babe Britney Spears had a major quarrel with her hubby Kevin Federline, over the latters smoking and excessive drinking, especially during her pregnancy.

According to Femalefirst, the couple had a huge bust up at the US premiere of "Charlie and the Chocolate Factory."

"Britney told Kevin to avoid the free booze at the party and top lay off the cigarettes," a source said.

"Kevin had a few glasses of champagne and a smoke and she just hit the roof calling him selfish," he added. Last week, Britney was warned she had to stop inhaling Kevin's second-hand cigarette smoke to ensure she had a healthy pregnancy. New York medic Holly Phillips publicly advised the singer to avoid inhaling cigarette smoke, slow down in the bedroom and give up fast food to give herself the best chance of a 'normal' birth.
