re: Non-pretentious, "down to earth" Hollywood celebrities

I worked at a very popular club in San Francisco while I was going to film school. Lots of famous people came through. Some notes:

Probably the coolest, laid back person I met was Gene Simmons. Kid Rock was really cool, although he tried to fight the DJ one night
Depeche Mode came through and they were cool and hooked up a bunch of free tickets to their show.
Christian Laettner was really cool and down to earth. Lots of sports guys came through here. My favorite was Jason Giambi as he always tipped me $100.
I also met Kobe Tai and Janine. I walked Janine to her hotel thinking I might have a chance and opened her hotel door to meet Jesse James who was her boyfriend at the time But they were both very cool.

Then there were the assholes like Charles Woodson and Vince Carter. Lars Ulrich is a total a-hole, I had to kick him out.

People are right about Sean Penn. He's a midget with a giant head and is a douchebag.

When I moved to L.A. to work in TV/Film, I got to hang out with a few people. Some really cool ones and some really not so cool ones.

The craziest I met was Brigette Neilson and Flavor Fav when they were together. They were running around the backstage of Big in '04 (VH1) doing all kinds of nasty shite. I also met Anna Nicole Smith that night and that's the show where she was all doped up. She was skinny at that time and was hot She was also very nice.
Green Day drummer was a total dickhead.

Plenty more, but I will finish by saying Luke Perry is one cool guy as we split a 6 pack on the last day of filming a movie and I smoked a joint with someone mentioned on here a few times and he really is down to earth
