In honesty, I don't think that marriages workout among celebrities for a few reasons. One, celebrities might feel pressured to enter a relationship. After all, they are in front of a public eye, and they might consider that they look bad if they are not always with a partner. Also, they have a higher social class, and in higher social classes like that, it's often seen as proper to marry someone within the class (though there are definitely exceptions). Because of these pressures to marry, a celebrity might not take the time to find someone that actually suits them, and might just pick someone else because they are famous and/or have money. They might not take the time to find true love like others would.
