Renee Zellweger and Kenny Chesney split over "fraud"

I am fascinated by the news that Renee Zellweger filed to have her four-month-old marriage to country star Kenny Chesney annuled on the grounds of "fraud." While she says "fraud" is a legal term and not a reflection on Chesney, that's kind of like saying that being a "convict" or a "bastard" is just a legal description. It's true, but it doesn't really help.

So, what does it mean? Based entirely on a bar review class on the laws of a state other than California that I took several years ago, I will say with 50% confidence that "fraud" in this context has to be something very fundamental to the marriage, and which, if Renee had known about it, she wouldn't have married him. Traditionally (I'm still talking out my ass here, by the way), this would have to be something like saying you were pregnant (or a virgin) when you weren't, or concealing a sexually transmitted disease, insanity, or the fact that you were already married. Interestingly, I seem to recall that lying about whether you loved the other person would not count--ahhh, institution of marriage, you beautiful thing! Back in the day, lying about your race could count. Of course, concealing your homosexuality might also do it. Let the unfounded speculation continue apace!
