Actor Bruce Willis makes sure his three teenage daughters' male friends treat them with respect by taking the boys aside and giving them "that little look". The Die Hard star has three girls with his former wife Demi Moore - Rumer, 18; Scout, 15; and Tallulah, 13 - and worries about the intentions of their adolescent boyfriends. The 52-year-old tough guy says, "I'm not hard at all. I just tell the boys I want to meet them - that's the only thing I ask for. I just give them that look, that little look. "I always put one of them in charge. If they bring a little group of guys over to the house to have a pool party or whatever, I just say, 'Dude, what's your name?' and he says, 'Uh, Cinjun.' "I say, 'Cinjun, you're in charge. If anything happens to one of my daughters, I'm coming to you first, and then I'm going to kill all your friends right in front of you, and you'll be last.'" He adds, "What we've done, as parents, is to try and send the girls out in the world with as much information about what those 16- and 18-year-old boys are thinking, and hopefully that'll keep them safe."
