Chris Pratt Posts Rare Photo of 'Cool Kid' Son Jack With Anna Faris

Only a week after his daughter, Lyla, turned 4, Chris Pratt's son, Jack, whom he shares with his ex-wife, Anna Faris, celebrated his 12th birthday.

Pratt paid tribute to his son with a sweet post on Instagram, sharing rare photos of himself spending quality time with Jack on a farm.

In the first snap, Pratt looked at Jack lovingly while they held milk bottles to feed the cows. Jack checked out the sheep and horses in the other photos, appearing to connect with the animals.

"Happy Birthday to my wonderful son Jack. I thank God every day for you sweet boy," said Pratt. "You are so smart, hilarious, kind, thoughtful, trustworthy and tough. I love you so much kiddo. Twelve!? I honestly can’t believe it."

Fans wished Jack happy birthday in the comments, with notes like, "Happy Birthday Jack! You are one cool kid ????," and "He looks so pure! Happy Birthday little man!??."

"Kids are just the best! It gets better as they get older..??," wrote a third fan.

One person commended Pratt for never showing Jack's full face in the photos to protect his identity, writing, "Cute pics! Thanks for shielding his face! Smart Dad!??."

Pratt does the same with his two daughters, Lyla and Eloise, whom he shares with his wife, Katherine Schwarzenegger. The couple is currently expecting their third child.

Pratt and Faris welcomed Jack in August 2012, a few years after tying the knot in 2009. They divorced in 2018 and since then, both have remarried. Pratt said "I do" to Schwarzenegger, and Faris married cinematographer Michael Barrett.

Faris is now a stepmother to Barrett's two kids from a previous marriage, an older daughter named Margot and a teenage son.
