"This photo was taken in my mother's house last May when we all celebrated her 78th birthday and Mother's Day together. I never miss her birthday, and because it's so close to Mother's Day, we celebrate both with a big family dinner every year. My mother is my best friend, and as a single father, she taught me everything I know about raising a child and being a good parent. It is rare that a man of my age still needs his mother for so many things day to day," the actor says on Facebook Timeline
