Is it normal to get jealous of other pretty girls?

I bet you're prettier than most of the celebrities you named off. Seriously, the majority of them don't look beautiful. Also, if you're receiving compliments then that says something.

Even though I'm a guy, I can still relate. What sets me apart from most guys is that I'm thin and I feel confident about myself. Appearance-wise, some women won't find me appealing, but others will. That's how the opposite gender works.
