Nick Lachey Becomes Jersey Shore's Ronnie!

It just might be the movie role of a lifetime for Nick Lachey: playing Ronnie Magro in Jersey Shore: The Movie!

Lachey greased up his hair, piled on the gold jewelry and did his best "guido" accent in a mock "preview" clip for a big-screen dramatization of MTV's reality smash that aired Friday on the Late Late Show with Craig Ferguson.

"Never fall in love on the Jersey Shore," Lachey-as-Ronnie says, "Unless it's with something you really wanna rock -- like an Italian girl or a Camaro."

Also joining Lachey in the fun: Book of Eli actress Mila Kunis as Snooki ("That's some good pickle!") and comedian Thomas Lennon as The Situation.

Intones the preview narrator: ""The only thing they love more than ham is the duck phone!"
