Anyone deal with friends turned famous?

I feel so weird around my "famous" friend.

He was a regular on a show last year and ever since then I get this rush when I talk to him. It's annoying, really. Why should it matter that thousands of people know who he is?

I feel like he's changing into this shameless person. He's still very young, 19, I believe, and there's a lot left for him to learn. This was his first big public project and I'm afraid his ego is going to inflate, I mean, he's an Aries and he's always sort of been in the spotlight in our social circle, but... I don't know. Has anyone else had to deal with something similar?

Being friends with famous people? It just instigates this feeling like "Oh, I'm important because I know you," which I'm well aware is not true and the idea of celebrity sickens me. I do long to work in film and television some day, but I could care less about my name much less my face (I'm a writer/director) being known at all.

We were at a party recently, he was drinking underage and got really nervous because a cop knocked on the door. Worst case scenario for a kid his age is a ticket and a class, right? And that's IF the cop finds his way in the house against our will. Anyways, he reacted in a nervous panic attack and was fretting about getting kicked off the show - which, by the way, is no longer on the air... or at least, he's no longer affiliated with it.

I've known him for five years and I've always felt a strong creative connection. Maybe I'm a little jealous, but not directly. I mean of him getting propelled into the mainstream of the industry and becoming more well known, the actual project he was a part of was pure dribble.

Sigh.

I know this isn't all that normal, but half of us are here for advice anyways, right?

Help?
