Chris Rock better watch his back when Lucious Lyon enters his prison confines in the new season of "Empire."

The hit Fox series started shooting on Tuesday and co-creator Lee Daniels shared a few behind-the-scenes photos and videos with Rock, the latest big name guest star, and Terrence Howard, who start the second season in prison together.

Following his arrest for Bunkie's murder in the season one finale, Howard's Lucious Lyons finds himself behind bars in an orange prison jumpsuit. It sounds like he's takes the brunt of his frustration and anger out on Rock's character, but the actor is happy to be working with the Oscar-nominated actor and director.

 "My first day was incredible. I worked with the great Terrence Howard. The great Lee Daniels," Rock said in Daniel's Instagram video.

Howard interrupted him saying, "And Terrence punched him in the stomach by accident. Four times."

But Rock wasn't fooled, "I don't know if it was an accident. He does have a reputation."

Ow! Now there's a low blow.
