Rob says he was especially close to Emilio, Charlie and their father, Hollywood legend Martin Sheen. "Everybody in their childhood has that family where you know you're going to be there on Christmas Eve," he says. "And on any given weekend, you're going to be maybe spending the night in the guest bedroom. That was the Sheens' house for me growing up."
Along with Emilio and Charlie, Rob says Tom Cruise—who moved to California from New Jersey to try to make it as an actor—was living at the Sheens' house for a period of time. "We were all competitive but really, really friendly," Rob says.
