The first time you discover that your favorite celebrity doesn't live up to your idealized version of them is kind of like walking in on Santa Claus fucking the Easter Bunny; not only are your childlike assumptions about the world shaken, but you've also discovered your parents are into some freaky role-playing. (Those scars last a long time. Trust us.) To wit, Vince Vaughn's bravura performance at Chi, submitted by a trusted Defamer operative who was practically sitting in his lap. Treating your admirers like shit is so money, baby!

Okay, so Wednesday night I was at Chi and saw a strange contingent of Hollywood peeps there, such as the guy who played Sue in Swingers and the dude who played Mr. MacDowell in Coming To America. (I know he's played other parts, but that's what I always think of him as.) There was also a Lorenzo Lamas-type bit-player meathead who I can't remember the name of, but he was all five-o'clock shadowed and intense. But that's not the point. The point is that somewhere around midnight Vince Vaughn showed up all scruffy, bloated and trucker-hat chic. He took up residence in the smoking area and hung out with some peeps.

So while me and my gal pal were debating whether to make our way over and tell him we were fans, he got asked by a couple young things to sign some autographs and he happily obliged, so we thought that was a sign that it's cool to make an approach. But then this guy went over and told him how his brother was a fan and asked if he could take a picture.

"No no, man, not right now, it's not a good time," La Vaughn said.

"Okay, no problem," the dude told him. "I completely understand. My brother really digs your work and thinks you're great."

La Vaughn's response? "Tell your brother I said to go fuck off."

And with that he turned back to his posse, leaving the dude to kind of stand there in shock and wonder if he really was just slammed for a compliment.

Needless to say, we did not approach. Actually, we left.

Sometimes we're gripped by the fear that stories of celebrities acting like pricks are incredibly tiresome, and we tuck them away as the fourteenth item of our weekly Hollywood PrivacyWatch clearinghouse. But you know what's never tiresome? Stories of celebrities acting like giant pricks to their fans. That shit never gets old!
