Last month, Kim Richards of The Real Housewives of Beverly Hills was arrested at the Beverly Hills Hotel for being drunk and disorderly. Cops had to drag her out of the bathroom where she was hiding and when she got to the station to be charged she kicked a police officer. In a follow-up appearance on Dr. Phil, Kim denied having a drinking problem but admitted that she did have drinks “a couple of other times” when she claimed to be sober. She cried pitifully and played the victim whenever Dr. Phil called her out. Kim’s three adult children were with her and they looked understandably hardened toward their mother, as if they were over her drama. Dr. Phil tried to get Kim to go to rehab, but she waffled. She kept saying that her daughter, Brooke, was getting married in Mexico and she didn’t want to miss it. (It was Brooke’s second wedding to the same guy, her first was shown on RHOBH.)

Kim eventually went to rehab (her fourth stint that we know of) after changing her mind a few times. She got furlough from rehab to go to her daughter’s wedding this weekend in Cabo, just like she requested, and she had a sober coach with her. Well guess what? At her daughter’s wedding, Kim got drunk, rude and slurry as is her default setting. She spewed a bunch of crap to Brooke and now Brooke isn’t even talking to her. Kim’s sober coach got so fed up she left. Predictably, Kim missed her deadline to return to rehab. Here’s more, thanks to TMZ:

Kim Richards melted down at her daughter’s wedding over the weekend to the point her sober coach quit, her daughter isn’t speaking with her anymore and those present say she was either on drugs or alcohol.

Multiple sources tell TMZ … Kim was clearly under the influence of something, although no one seems to know what. Our sources say whatever Kim took or drank, she did so in private, but when she interacted with people at the wedding she was “a mess.”

We’re told Kim was saying horribly nasty things to her daughter, Brooke, right after the wedding. We’re told Kim was cursing out the groom’s family and was generally belligerent. The bride has vowed she won’t speak with her mom again.

As for the sober coach … we’re told she couldn’t control Kim and left Mexico immediately after the wedding.

Our sources say Kim is still in Cabo and she’s gone radio silent. The rehab facility gave her a pass to attend the wedding but gave her a deadline to return Monday, which she has not done.

Yeah, that was easy to see coming. I know Dr. Phil is a quack but he does call people on their bullsh*t. He said one thing to Kim that stuck with me. “I’ve never yet seen an alcoholic that reports things fully and accurately.”

Years ago, during the first season of RHOBH, I was on Kim’s side in the ongoing battle between Kim and her sister, Kyle. I thought that Kyle was being harsh to Kim when she called her insane and told her that people were sick of her drama. Kim went to rehab back then but it’s rinse and repeat with her. Now that I’ve seen Kim continue to spiral into alcoholism and denial, I get where Kyle was coming from. It must be so hard to deal with an alcoholic sister like that, not to mention a mother who brings all that drama to her daughter’s wedding.

Paris Hilton posted this video of her aunt Kim addressing the bride and groom. This must have been before she hit the sauce heavy.

Such a beautiful moment between The bride & mother of the bride. ?? Love you @KimRichards11. Congratulations @BrookeWiederhorn & @ThayerWiederhorn. #SoulMates ???? #WiederWedding
