Should i sell stories about my famous brother to the tabloids?

I'm torn a bit between saying "do it for Mom" and "just because he's a jerk you shouldn't join him". But if you do end up telling all....you better have some sort of proof and not just your word against his especially when you are angry with him. Too many people would say you were just trying to "get him". I guess what I'm really saying is to think long and hard before you do anything.
