K-Fed has a smoking gun in his quest to ‘divorce that bitch and then get my boys away from her.’ Kevin has obtained video footage from fifteen surveillance cameras that Britney installed in their $12 million mansion is Malibu that feature the pop tart drugging, boozing, and beating up her then hubby.

According to tab tattles: “In one tape, Britney slaps Kevin after screaming at him about a weekend he spent in Vegas. In another incident taped Britney whacked Kevin with a frying pan. Kevin was going to use the frying pan, but Britney grabbed it and hit him with it when he turned his back, said the insider. He grabbed the pan out of her hand and walked away, but she hurled an ashtray at him. He dodged it, and it hit the sliding glass door. In addition to the video tapes, Kevin has voicemail tapes of Britney admitting she was out drinking with friends, the insider revealed. Kevin believes that Britney lets the boys run around with dirty diapers because she’s too lazy to change them.”

“It’s more than getting custody of the kids- in Kevin’s mind it’s rescuing them. He thinks Britney is an unfit mother and he wants his children away from her ASAP,” says a Federline insider.
