Freddie Prinze, Jr. met his wife [Sarah Michelle Gellar](/show/segments/view/celebrity-face-/) while filming 1997's *I Know What You Did Last Summer*, and these days the couple is enjoying their new role as parents. "She's the cutest!" beams Freddie about his baby Charlotte Grace. "She sleeps, she eats, she laughs - we've been really lucky." But does Freddie actually change diapers? "I can change a diaper with the best of them," he brags. "In under 40 seconds!" Recently a dream of Freddie's came true when he joined the cast of *24*. "My wife and I have watched it religiously for years," he says. "If you're a fan of the show, you've sat there and you've wanted to be Jack's partner because you would be the one who wouldn't screw him over. So when I got the chance to do it, I took it!" The actor jokes about the lengths the show goes to in order to keep the plot lines a secret. "If you say something, they'll kill you," Freddie laughs. "So I don't say too much. I say, 'That's a great show,' and outside of that I watch my step!"
