Though he dates many beautiful ladies in his films, but Men In Black 3 actor Will Smith is pretty worried about the future affairs of his 11-year-old daughter Willow. The star said, despite his daughter is not big enough to have boyfriends right now, yet he is already tensed about the suitors she might bring home in the future, People Magazine reported. "It's coming, and I'm nervous about it. Having two boys and a girl, I realise that boys take trouble to other people's houses, and girls bring it home, Will said. "So, the thing we are struggling with is the rules, and setting fair rules for the boys and for Willow, but she's not having any of that," he added. The actor wants to plan in advance how he will deal with the situation. "When Willow does bring a boy home, I'm going to screen him and find out everything about him. And that's going to happen when she's 40, when she's allowed to go on dates!" the actor stated.
