Following in the footsteps of Diddy and Taylor Swift, [artist id="1241636"]Ashlee Simpson-Wentz[/artist] and [artist id="1235716"]Pete Wentz[/artist] will make their big debut on "CSI: NY" on Wednesday (March 18).

In a clip released early, fans got a taste of what to expect from the pop stars. The episode casts them as Chester Byron and Lila Wickfield, a young couple entangled in the world of drug-dealing.

"Well, it's not quite Bonnie and Clyde, but they're caught up in something, and we have to figure it out, of course," the show's star Gary Sinise told CBS' "The Early Show."

Pete sounds pretty excited about playing a criminal, telling People magazine, "I wish I got the chance to be murdered or rob a bank, but I heard the makeup [takes] much longer for that."

In the past, the Wentzes appeared together on "Dog Whisperer With Cesar Millan," and they've each done some acting work on their own. "It's easy to play passionate roles with the person you love," Pete told the magazine. "There's nothing weird about it when you love the person."

And this won't be Ashlee's last TV role: The singer/actress was recently cast in the remake of "Melrose Place" expected to air on the CW this fall. "I'm thrilled to be joining the cast of 'Melrose Place' and look forward to being a part of its new generation of residents," Simpson-Wentz told MTV News.

On the show, she'll be playing Violet, a small-town girl who is very manipulative, using her girl-next-door charm to get what she wants.
