Hollywood marriage is when two famous movie stars or celebrities get married. Just like when your friends' parents get married, but these people are famous and everyone knows who they are. Sometimes these marriages last a long time, like a fairytale, but sometimes they only last for a little while. It's like when you have a toy that you really like, but then you get tired of playing with it and want to trade it for something else. Sometimes people get tired of being with each other and want to go their separate ways.
In Hollywood, people often have to travel a lot for work, which can make it hard to be with their spouse all the time. They also have lots of people watching them, which can make it harder to keep some things private. This can lead to some people feeling like they want to be with someone else or feeling like they need some space. But sometimes people can work things out and stay together for a long time. It's up to each couple to decide what's best for them.
