The 37-year-old actor will play the 39-year-old actress’ new love interest in Season 4, according to Entertainment Weekly.
Pratt will portray Nick, a “charming” horseback-riding instructor who piques Christy’s (Faris) interest. The character is nephew to Christy’s friend Marjorie (Mimi Kennedy), who declares her relative off-limits.
The “Take Me Home Tonight” co-stars have also collaborated on the films “What’s Your Number?” and Movie 43. They married in Bali, Indonesia, in 2009, and share 4-year-old son “Jack.”
Pratt had told Parade in September that he will take a six-month break from acting to spend time with his family. He recently finished filming “The Magnificent Seven,” “Passengers” and “Guardians of the Galaxy Vol. 2” in succession.
“I’ve been on the road for 14 months — I did three movies back to back to back — so I’m taking six months off,” the star said at the time.
“I’m taking Jack to Jack’s Beach — which is what we named the little stretch of beach on an island up on the San Juan Islands where we got a place,” he revealed. “We’re going to go back to the fort we built … and see if that’s still there. If not, we’re going to build it again.”
“Mom” will return for a fourth season Oct. 27 on CBS, with Pratt’s guest spot slated for early 2017.
