Chris also had the chance to bond with twin babies in the NICU — a special experience given he and his wife, Anna Faris' son, Jack, was born premature.

"Ever since Jack's premature birth, we have a special affinity for the NICU. Today I spent a little time with Coen and Zion, twins who were born too early only a pound and a half each. Thank you to the doctors and nurses at @seattlechildrens. The boys are doing fine. Although they're both missing their big sis," he shared.

Everyone seemed so happy to have such a famous visitor!

"What an awesome kid. Great parents and from a great family," he captioned the above image.
