Young parents Britney Spears and Kevin Federline recently had a blow-out fight, but reports of a divorce were apparently premature. The couple had a heated argument Nov. 30 that resulted in Federline bolting from the couple's Malibu, Calif., home. A friend told People magazine said Spears was apparently overwhelmed with being a wife and new mother and blew up at her husband for no reason in particular. The pair then took to the clubs with Spears seen out until the wee hours "with the girls" in Los Angeles and Federline doing the town with his cronies in Las Vegas, People said. However, as of Tuesday, the couple and their 3-month-old son were back together in their Malibu home. "This has happened before," an insider told People. "They always work it out."
