"They're so cute. I'm constantly getting a kid fix," Aniston, 41, tells Entertainment Tonight of hanging around Adam Sandler, Nicole Kidman and Dave Matthews' children.
The pack of kids – who apparently became fast friends – includes Sandler's daughters Sadie, who turns 4 on Thursday, and Sunny, 18 months; Kidman's daughter Sunday Rose, who will be 2 in July; and Matthews's son August, who'll be 3 in June.
The way the Just Go With It set is organized, the kids are never far from the action. "We all have these little cabanas in a row where our dressing rooms are, and one of them is the nursery," says Aniston. "Which is pretty fun to watch. Filled with children."
Sandler's daughter Sadie is warming up to Aniston, though it took a little time. "50/50 Sadie, I call her," Sandler says. "It's either 'Who's that girl?' or she hugs you out of left field."
"She's so sweet," says Aniston.
