Am I right to get mad at my boyfriend for telling me a girl tried to flirt with him?

Long story short, my boyfriend has a lot of friends and last weekend he went out with some of them. He was telling me how he had a good time, and they were all taking pictures with him. And then some woman at the pub asked him if he was a celebrity or smthg. I got mad at him, as in why would he tell me such thing, and he was like : I was telling you about how it went with my friends, it wasn't about her. We had a fight and he hasn't talked to me since.
