Looking for some shoujo manga in which the girl has a famous or rich/her boyfriend becomes famous. Can be famous for anything, singing, acting, owning a business, anything.

Some of the ones I have already read are:

Hairstyle Amanojaku Shiyou
Private Prince
Sugar Addiction
Cocoa!
Sugar Pot
Hanayome-sama wa 16 Sai

If you've ever thought or said "Nice Guys finish last" and really meant it, then you should probably read this LJ post by DivaLion. It's incredibly insightful whether you're male or female.

From a bumper sticker I like:
"If you're gonna ride my ass, at least pull my hair."
