Is this worth feeling upset about

Idk why I get so angry when my bf mentions this certain celeb that he has a crush on. It’s because he used to be so rude & disgusting about her such as if it were to be between me & her, he would choose to fuck her any day and he would throw it in my face. Do I have a right to be mad about that? I may come off insecure but shit like that hurts self-esteem. I could’ve clapped back & mentioned a male celebrity, but I don’t like hurting people’s feelings or making them feel insecure about themselves. He follows her & always looks at her posts & it just makes me uncomfortable at times. Idk, am I wrong
