NCIS: Los Angeles star LL Cool J sat down with ET's Nancy O'Dell today to talk about tonight's much hyped episode, and he promises it's going to be a juicy one!
"I would call it the end of one chapter on TV and the beginning of a new chapter in music, it's pretty deep," LL says about the seriousness of the episode. "The teaser is that there's only one word I can use -- and that's betrayal."
He also jokes about his character Sam Hanna's newly uncovered romantic side.
"Well you know, Sam is capable," he laughs. "We get to see Sam interact on a romantic level so there's a little romance, we get to explore some of his home life ... we find out that he's not just a one dimensional guy that runs and shoots and jumps, but has some other vulnerabilities and some other feelings and some other things happening."
