Will Kevin Federline get the kids? Following Britney Spears’s latest round of erratic behavior, her estranged hubby wants sole custody of their two children, according to Life & Style.

Spears was recently spotted driving with her younger son Jayden facing forward in his car seat, not backward as federal guidelines require. And earlier this month, he was photographed grabbing his mother’s cigarettes. On July 18, she stripped to her skivvies on a beach in front of photographers and reports of bizarre behavior at an OK! magazine shoot have friends seriously worried about the Toxic singer. Spears wants K-Fed to sign a joint custody agreement, but he’s reportedly refused.

“Kevin is convinced she’s not fit to raise the kids,” an insider told the mag. “He’s done tolerating her behavior and is gearing up to fight for full custody.”
