“Michael and I were kind of early empty-nesters, because our son Dylan is off at college and our daughter, Carys, goes to school in Europe,” the “Chicago” actress explained on the “Today” show. “So all of a sudden they descended on back into our home and it was just wonderful. It was just breakfast, lunch and dinner all together.”

“Supposedly…we’ve been much better than a lot of his friends’ families,” she quipped. “He said, ‘Mom, you have no idea. James is not talking to his dad, he’s not talking to his mom.’ And I said, ‘Well, we’re doing pretty well.'”
