The two actors have signed on to play a married couple in the new film, "A Little Game Without Consequence."
Diaz and Carrey co-starred in "The Mask" in 1994, the film is hailed as starting both actors' careers and sending them in to superstardom.
"A Little Game Without Consequence" is about a married couple who, after five years together, decide to spice up their marriage by telling friends and family that they are splitting up. Only instead of support from them, the couple learns that most of their friends and family didn't think they two were meant to be together in the first place.
The film is set to start shooting next month in New York.
