Having a celebrity crush is pretty normal. It results in a set of impossibly high standards the said famous person would likely fall short of too. They might feel more attainable as actual people rather than fictional characters.

What is it called when you are in love with a celebrity?

Erotomania is a rare mental health condition that happens when someone is fixated on the idea that another person is intensely in love with them. The other person may be a celebrity, wealthy, or of a high social position. The condition is also known as De Clérambaults syndrome.
