Would you be mad

Last night my boyfriend replied to a celebrities Instagram story probably thinking that she was going to post a nude. The picture says “let me go nude” I think he didn’t get the message that she meant nude as in the nude colors of her clothes. He said it doesn’t count cause she’s a celebrity but I still feel hurt. Is there a reason I should be mad or am I just overreacting? He doesn’t text other girls or like pics of girls he just likes sport videos or pictures so I don’t know if there’s really any reason why I should be upset
