Kathy Hilton has just made an odd move.

Kathy Hilton Returns To Twitter, Tells Fans She's Praying Herself To Sleep After Kim Richards' Arrest

Just one week after her feud with Kyle Richards was revealed on The Real Housewives of Beverly Hills, Hilton and her husband have made plans to celebrate his real estate company's holiday party at the Beverly Hills Hotel.

“The Hilton & Hyland Christmas party is at the Beverly Hills Hotel this year,” a source told Radar Online on Wednesday. “For the last two years Kathy had the party somewhere else, but now she’s moved it back to the Beverly Hills Hotel, which seems a little rude considering Kim’s recent history there."

In April of this year, Kim traveled to the hotel after indulging in a glass of vodka at her daughter's house, and after becoming beligerent at the hotel's Polo Lounge, she was asked to leave, which she refused to do. Once police arrived, things became even more intense with Kim assaulting the police officer.

In addition to a battery on an officer charge, Kim was charged with trespassing, resisting an officer and public intoxication. Then, during her court hearing, it was announced that she would be banned from the hotel.

“Kathy cares about her sister, but there is nothing anyone can do about the situation,” the source explained. “She has been wanting Kim to clean up her act for 30 years. It is exasperating.”
