Jake Gyllenhaal's Learning from the Kids in His Life

Jake Gyllenhaal is learning how to grow up with the help of the kids in his life.

"I've learned so much from the kids in my life, and somehow they just become the center of your life and the way you look at things," he told reporters at a press conference for his new film Brothers in reference to his niece Ramona,3, and girlfriend Reese Witherspoon's children, Ava, 10, and Deacon, 6. "Obviously I exist in my girlfriend's world and my sister's world in a different way, but it's opened my heart and I feel much more grown up and want to be grown up as a result of it."
