LL Cool J's chiseled abs and protruding muscles aren't just for show, the "Mama Says Knock You Out" rapper protected his own, when he took down an intruder with his bare hands this morning at his home, according to the gossip website TMZ.

Law enforcement sources say, the assailant entered LL's Los Angeles property around 2AM, but didn't expect to run into the massive 6'2 actor.

The "NCIS Los Angeles" star heard unknown noises in his home, decided to investigate and found the man, whose identity has yet to be disclosed, traipsing through his house.

When the intruder tripped his alarm, LL jumped into action and physically defended his turf. He managed to restrain him until authorities arrived on the scene. The suspect was arrested on burglary charges and sustained a few bruises during the scuffle.

The rapper turned actor, who will be hosting the Grammy awards this year, has probably transitioned into the movie business because he feels radio stations control the type of music their audiences are subjected to.

"The biggest problem to me in music right now is radio," LL said in an interview with Forbes. "I think that radio has gotten to the point where, you know, you hear the same thing over and over again, so much because you have a group of people controlling it, no disrespect, they're doing their jobs, but you have a certain group of people that are controlling the airplay to the point where it makes you want to throw up. It's crazy, the airplay situation. There used to be a time, and this is a good thing, where you would hear different kinds of music and different genres of music playing back-to-back. But what has happened is, now they've gotten to the point where the only audience they can hold on to is 14 and younger because everybody else is online, grabbing their music, creating their playlists, listening to what they want to work out to because the radio drives them crazy. I think at some point, some radio station some where is going to have to say, 'You know what? It's time for us to program a little differently and trust that the music's great.'"

One of LL's motto about life and work is "Do it well or not at all."  He told RadarOnline.  He certainly did very well today.
