(CMT Offstage keeps a 24/7 watch on everything that's happening with country music artists behind the scenes and out of the spotlight.)

Miranda Lambert will make her television acting debut on the episode of Law & Order: Special Victims Unit airing Wednesday night (Feb. 8) on CBS. And it may be the only acting she does because this is the one show she really wanted to be on, she tells CMT Insider. "I have all of them TiVo'ed. I watch the marathons. I love them. And I never wanted to act. I still don't. I don't want to be an actress. I just wanted to be on that show mainly so I could be a groupie and get my book signed and everything," Lambert admits.

"I actually played a rape victim, which was crazy to go from never acting to going to such a serious thing. I have a pretty small part, but it's big to me because I've never acted in my life," she said. "It was hard. I was really, really nervous, like about to throw up all day. I'm playing a character opposite of my personality, and I'm having to act with people that are actually amazing actors, so it really pushed me out of my comfort zone." And when the show's star detective, Mariska Hargitay, walked into the room, Lambert had to remind herself to be cool. "I'm nervous to watch it," she said.

There is reportedly a hostage situation in this episode. I wonder what would've happened if Lambert had brought gunpowder, lead and kerosene with her on the set.
