Famous Breakups - Blonde to Brown, and vice versa

This is my attempt to reduce cheating by men on their spouses to one simple issue: that being hair color.

Tiger Woods has a beautiful blonde wife.

Who is he cheating on her with?

Brown haired women.

Men are seemingly this simple.

Further, I think women know this: hence the popularity of brunnettes getting blond streaks, and vice versa. This search automatically popped up in google when i started typing in blonde.

Maybe some women think that this will keep a man from straying? It's hard to be reductionist here, but if you are a celebrity gossip mongerer, I am sure you will find this pattern all over the place.
