Britney Spears had two guns in the house where she held her two sons hostage during Thursday night’s custody battle standoff, according to a new report from a British tabloid.

NOTW claims that a Kevin Federline insider told them that the situation escalated after K-Fed called his legal team, who in turn called the authorities, because two guns were believed to be on the premises.

“K-Fed was terrified. He realized she had a gun where she was holding them.”

“Kevin knew she was on the edge and might snap at any time. Knowing there were two firearms in the house, including the Beretta, he wasn’t taking any chances— hence the massive police response.”
