LL Cool J may be in his mid-40s, but the New York rapper is still in great shape.

Just ask the would-be robber of his Los Angeles-area home, whom LL detained around 2 a.m. last night, according to TMZ. Before long, police arrived and dealt with the perp, who, may have suffered broken bones while fighting with the LL.  A rep told the site, "He is committed to keeping his family safe and is cooperating with authorities."
