Former Karate Kid star Ralph Macchio is all grown up, himself a 48-year-old dad to teenagers Julia, 17, and Daniel, 14. As an experienced parent, he offered up words of wisdom for Ugly Betty costars past and present, Ana Ortiz and Rebecca Romijn, both recent first-time moms. Tops on his list? Stay flexible! “It’s the toughest job in the world,” he notes before adding,

Joking that he’s “still looking” for the parenting rule book, Ralph says that his own kids had a curious reaction to his fame. “They’ll look back and, if a movie’s on television, they’ll remind me of how much better I looked back then,” he says.

When Daniel was still a child, he stumbled across a bundle of newspaper clippings and magazines from the Karate Kid days.

“He came up, and was like ‘Oh my God, Dad was huge, and we missed it,'” Ralph recalls. “He really enjoyed the Ugly Betty run because he was the one who went with me when I auditioned for that, and I’m on for a second season now. He’s like, ‘See? You should bring me along more often.'”

Father and son are “buddies,” Ralph says, enjoying ball games and vacations together. Daniel “wants to be a pilot,” and it’s a career path Ralph says he supports — nervously! “He took his first flight lesson for his birthday,” Ralph explains. “That’s a gift we got him.”

Julia, meanwhile, is preparing for college and a possible career in the arts. “She is very close with my wife, which I am thrilled with,” Ralph reports. “Mother-daughter closeness is very good, especially launching into those years.” He adds,

Julia and Daniel are Ralph’s children with Phyllis Fierro, his wife of 22 years.
