"#HappyThankgiving #12thMan," Pratt, 35, captioned a Twitter picture of the trio on Thursday, Nov. 27. The Parks and Recreation actor looked like a proud dad as he held the couple's 2-year-old boy in the air.
Later that day, Pratt also expressed his gratitude via his official Facebook page. "My family and I have so much to be thankful for this year," he wrote. "Thank you to the men and women of the armed forces. We love you!"
Indeed, Pratt has had an incredible 2014, and is poised to have yet another successful new year. The Everwood alum achieved bonafide blockbuster movie star status with his sci-fi adventure Guardians of the Galaxy back in August. He also hosted Saturday Night Live in September, and is already receiving buzz for his upcoming role in Jurassic World.
"WHOAAAA!!! Y'ALL SEE THAT TRAILER?" he tweeted after catching the film's commercial on Thanksgiving Day. "#JurrasicWorld #Run!!!!" Jurassic World, the fourth film of the Jurassic Park franchise, is set to hit theaters on June 12, 2015.
