Maybe a little bit, but I would not say that she is entirely overrated. I think the level that her fans put her on a pedestal is a bit too much. They see her as a kind of goddess which seems like a stretch. However, with that being said, she is pretty glorious.
She started her massive career as a member of the trio called Destiny's Child which was a popular girl band of the late 1990s. From there she branched out on her own eventually and created an incredible life for herself. It is easy to see why super fans treat her as royalty, amazing talent, stunningly beautiful, and a kind person.
