Paris Hilton's neighbors in the posh gated enclave of Mulholland Estates are furious that the hotel heiress threw her Christmas party in the middle of the week and are hoping she moves out of her Beverly Hills mansion, Breaking Celebrity News is exclusively reporting.

Hilty threw her annual Christmas party last Wednesday, and there were more than 100 people in attendance. Guests visiting Mulholland Estates must check in at the front gate, and most of Paris' guests all descended at the same time, causing a huge back-up.

"Paris' parties are legendary. She always goes all out. Non-invited guests that were going to visit other people's houses had to wait almost 35 minutes in line on a Wednesday night, just to get into to see the person they were going to visit. Paris does provide valet parking for party guests, and this clogs the streets around her house. Paris is the neighbor from hell," an insider tells Breaking Celebrity News.
