From Crazy Days and Nights:
"How dumb can someone be? You may have noticed that there is an A list aging, but not old film star. Actually not A list. He's definitely A+. Some might even throw on another plus. Anyway, you will notice there is a certain woman he dates for a month or two and then she disappears. She then returns in six or seven months for another month or two. This cycle has been played out for a long time. Turns out that she is dumb. (How dumb is she?) I'm glad you asked. She is so dumb that our A+ actor has got her pregnant at least three times. Each time he tells her that he has had a vasectomy and so she can't possibly get pregnant. She always believes him and is always getting pregnant. In fact when she gets pregnant is when she disappears. Seems that is the actor's goal each time."
The culprits: Possibly George Clooney and Krista Allen. They have been on/off since '03. Split dates 12/19/03, back together, split 3/19/04, back together, split summer '05, back together september '05, split again.
(Loose definition of an A list star from CDAN: A List Stars--- Shine brightly, consistently, and even folks that live in the middle of nowhere have heard of them. They can carry a film on their name and earn maga-bucks. My ideas would be Reese Witherspoon, Julia Roberts, and George Clooney. You probably won't see these stars getting trashed at the local nightclub in your tabloids )
