Another female celebrity who reached her peak in the ’90s is Britney Spears. It’s likely that many of us even had posters and CDs of the star, though nowadays most of us just feel sorry for her. She reached incredible fame as a teen with her music. Even to this day, she’s the world’s best-selling artist. Her famous head-shaving incident made headlines around the world, and only just received control of her finances after being put on hold. It sounds like she couldn’t handle the stress that comes with being famous. For years, the star has struggled with substance and drug abuse, and many people worry about her well-being to this day (via Fox).
