Chris Pratthad quite the night on Sunday.

The 39-year-old actor cheered on MMA fighter Adel Kyokushin Altamimi during his big Bellator win after walking out with the athlete during his introduction. The two train at the same gym in Los Angeles and Pratt has often showed off his love for the sport on social media.

“So proud of my brother on his amazing win tonight. Made a major splash at his @bellatormma debut. As he will tell you, God is good!!!” Pratt captioned an Instagram of the two celebrating after the match.

Pratt also posted a compilation video of the best moments of the night, including the beginning when the actor walked out with the fighter before his match.

“Take a deeper look at the story of Adel AlTimimi @kyokushininjaformer Al- Qaeda hostage and now @BellatorMMAfighter,” Pratt wrote on Twitter before the match. “Even if MMA isn’t your thing, the humanity of his story will move you. As Adel will tell you, God is good!”

Altamimi is an Iraqi-born fighter who worked with U.S. Marines for 4 years in Baghdad,according to Unbreakable Performances CEO and actor Jay Glazer.

Also at the match were Spencer Pratt and Heidi Montag with their son Gunnar, and the two took the chance to have some fun with Pratt and their last name. (Though they share a last name, they’re not related.)

“This is a family outing,” added Spencer before Pratt joked that he hasn’t seen his “nephew … since the birth.”

“He’s grown so big!” theParks and Recreationalum quipped in the video as he touched the little boy’s arm.

“Pratt family outing,” Spencer jokingly captioned the post.
