They're getting ready to become a family!

Chris Pratt picked up son Jack, whom he shares with ex-wife Anna Faris, for dinner with his new fiancee Katherine Schwarzenegger last night. The trio dined in Santa Monica and appeared totally comfortable and happy together. Katherine, 29, will be a first-time mom to Chris' boy, and we're going to go out on a limb and predict the new couple will have more children of their own together.

Meanwhile, Faris has been nothing but supportive of Chris' relationship with Kate. She congratulated them on Instagram after news of their engagement and she happily gives Jack over to his dad to spend time with him and Schwarzenegger. The couple even have in their divorce settlement the agreement that they'll live within five miles of each other while Jack's in elementary school. How smart!
