Confessions of a Hollywood Doorman

Ever wonder how hot Hollywood nightclubs decide who is getting in their exclusive establishments? Who will be denied? Why some celebrities get in and others do not? TMZ has all the answers. We spoke to a doorman at one of the most exclusive places in Hollywood and he spilled all the secrets of the trade.

"You need to be on the permanent guest list." Nightclubs in Hollywood have guest lists that feature people who will always be treated like royalty. Our source says "this list is about 300 individuals." Paris Hilton, Lindsay Lohan, Jessica Simpson, and Christina Aguliera are a few names at the top. Second, you can call and make a reservation if you have endless amount of cash (Brandon Davis, Stavros Niarcos) but even with a reservation, nothing is for certain. Celebrities: You have to be a hot property right now (not you Bobby Brown), as even being "famous" will not guarantee entry.

Our spy tells us there are always exceptions to the rules. "Mike Tyson was let in once because we felt that if we said no he might start boxing with the staff!" Being female usually works in your favor, but even Tara Reid will be turned away if she shows up with 5 guys. Take notes from Keenan Ivory Wayans, "he wasn't on the list but he was with a date and looked embarrassed, so I let him in."

Proclaiming your A-list status is also a "no no" with the doormen. On one occasion, Joaquin Phoenix, tried to enter through the back door (to avoid photographers) and was told to go to the front. Mr. Phoenix replied with, "You're making a a big mistake! Don't you know who I am?? I'm kind of a big deal."

Bottom Line....Yes, if Paris is on her way in, you're going have to wait.
