Guys , why would a guy say this?

Me and my friends with benefits were talking randomly and I jokingly told him he looks like a celebrity guy who’s a basketball player and showed him a picture. He looked at it and said “Is that the only reason you like me because I look like this guy” which I thought was a weird response.
I just wonder why he said that lol I mean I’ve never had another friends with benefits respond like that. And if he had did the same I wouldn’t respond like that
