Larry King and wife Shawn did not have prenup according to sources

Why would a man of Larry King’s obvious intelligence and sophistication marry a woman in the state of California without a prenup? The New York Daily News is reporting that there was no prenup. Incomprehensible. And he was on his death bed too. Well, he was in a hospital getting serious surgery when they tied the knot. Oh wait. That might explain it. He thought a) she was smoking hot and b) he was gonna die anyway so what the heck.
The heck is that 13 years later, she filed for divorce and he’s worth over $150 million dollars most of which was earned during his California marriage. She is going to walk away with at least half of that. Larry. What were you thinking? How do you get married to a woman 26 years younger than you without a prenup? Happy endings?
