An intruder broke into LL Cool J'S home in L.A. on Tuesday night, but unfortunately for him, LL was home at the time and he was feeling confrontational.

According to reports, LL heard something at around 1:00 A.M., and went to investigate. He discovered an intruder in his kitchen, and proceeded to beat the crap out of him.

Police sources tell the "Los Angeles Times" that the intruder "rushed" him, which led to a "knock-down drag-out fight."

The cops showed up shortly after that, and arrested the guy. He was hospitalized, and is being treated for several injuries including a broken nose and jaw.

It definitely doesn't sound like this guy was a professional robber. He's being described as a "transient," and officials believe he may suffer from "mental issues." He's 58 years old.

LL's rep says: "[He] and his family are safe and thank everyone for their thoughts and concern. As a father, husband and citizen, he is committed to keeping his family safe and is cooperating with authorities on this private matter."

This story makes you want to hear "Mama Said Knock You Out," doesn't it?
