My totally guess is that there's some truth to this story, *and* she's a gold digger.
Why do I think there's truth to it? First, because I believe that anybody who would marry a scumbag like Kobe, and stick with him after cheating because he bought her a huge diamond, probably isn't a great person herself. Second, the housekeeper quit. If things were all hunky-doory there, there's no way she's walking out on the Bryants.
That being said, it looks like she's seeking a pay day.
