It is such an act. A friend of mine worked PR at the Olympics in China. He told me that Kobe visited hookers pretty much every day, and would tell his wife that he was going to photoshoots or other stuff like that.
I could care less if he wants to break Wilt's record (in the bedroom), and I have no sympathy for his wife either if she hasn't figured it out by now. However, I can't stand that fake "I'm really just a family man crap." It insults my intelligence.
He hit some crazy shots today, though.
