Ryan Guzman Tells Us He Was Totally Terrified Of Singing In 'Jem And The Holograms'

He'll be fine... we hope.

Ryan Guzman has already proven that he can dance, but can he sing? The answer is not so encouraging.

Speaking to MTV News at a press day for his film "The Boy Next Door," Guzman said he stepped out of his comfort zone to play Jem's main squeeze Rio in the live-action "Jem and the Holograms" movie. In fact, he had never (ever!) sung before getting cast in the film.

"I sang for the very first time for 'Jem and the Holograms,' which is also very scary because the people I was singing with are unbelievable," he said.

Okay, we're sure Guzman actually sounds fine in the film. After all, producer Scooter Braun -- the maestro behind Justin Bieber -- has already given the soundtrack his stamp of approval. And he knows a hit when he hears one.

Based on the cult Hasbro animated series from the 80s, the rebooted "Jem and the Holograms" will follow Jerrica Benton (played by newcomer Aubrey Peeples) and her rockstar alter ego Jem, the truly outrageous lead singer of band Jem and the Holograms. And Guzman's character Rio Pacheco is her road manager/love interest. (We can only hope their duet is as epic as this one.)

And just in case you were wondering, Guzman will not be busting moves in the film. "I think I've proven my dancing skills," he said.

The music may be contagious, Jem, but the dancing definitely isn't.
