The trio has been vacationing in Hawaii where Jim and Evan, 7, made sand castles, splashed in the surf and went kayaking.  Evan, who is autistic, seemed a bit unsure about the whole kayaking thing at first but Jim was so careful and comforting, it made for a great adventure.

RadarOnline.com broke the news earlier this month that Jim, 47, is going to be a grandfather!

Jim's daughter Jane and her fiancé will be first-time parents in December and Jim said he couldn't be more "excited."

"Jim is a natural-born dad," a friend of the actor told RadarOnline.com. "He's always been devoted to Jane and he adores Evan."
