Is K-Fed (remember him?) jealous over Britney Spears' new beau? Sounds like it! The wannabe rapper has been talking shizznit about Brit's new BF, Howie Day. "When Kevin heard they had a sleepover at her house, everyone wanted to know about it," a source tells Star. "He…said he guessed you have to head to the dump to find trash, referring to how Britney and Howie met while in rehab." When K-Fed calls someone trash, you know the person has to be pretty bad.

Kevin's not the only one who isn't fond of Howie. Brit's friends aren't too pleased with her new match, and for good reason: he was arrested in 2004 for allegedly locking a fan in the bathroom of his tour bus when she wouldn't hook up with him, and in 2005, he was charged with verbally abusing a flight attendant while under the influence of sleeping pills and alcohol. "People have told Britney point-blank this guy has a permanent barstool in the Loser Lounge," a friend says. "I was with her when one of her most trusted girlfriends told her, 'You cannot let this guy into your life -- after he gets a little publicity he will be gone.' But when people say stuff like that, it's music to Britney's ears. She likes the drama."

Oh, really? We would have never guessed...
