British director Guy Ritchie, 32, who also happens to be married to Madonna, admitted to the German magazine Stern that it "is still too early to say how my wife will influence my life. But I do already know that it's sometimes hard work living with her." As for where the tension develops, Ritchie confided to the large-circulation weekly, "My wife has great acting talent, but she also has a headstrong personality. A director would have to guide her in the right direction." On the issue of living with a celebrity, Ritchie said, "I can understand that the whole world is interested in my wife. That's even why I married her." Beyond that, Ritchie, who is the father of Madonna's son Rocco, who is approaching his first birthday (Madonna, 42, also has a daughter, Lourdes, 5), insisted that theirs is a "normal small family."
