Kim Richards left a sober living facility last week to attend daughter Brooke Brinson's wedding on Saturday, and now, according to a new report, the reality star is headed back to treatment.

Kim Richards Has Returned To Social Media

Although it is unclear whether the Real Housewives of Beverly Hills star will reenter the Los Angeles treatment facility where she was previously, TMZ reported on Sunday that Richards' trip to Mexico was only temporary.

"Kim Richards was front and center for her daughter's wedding Saturday in Cabo, but it's just a night out before returning to rehab," the site explained. "Kim, who had a sober coach present, did not drink and she's returning to rehab, where she's been since shortly after her drunken night at the Beverly Hills Hotel which led to her arrest and criminal charges."

Kim Richards Is Facing Two Years Behind Bars For Her Drunken Rampage Last Month

Brinson and her husband, Thayer Weiderhorn, tied the knot in Cabo San Lucas on Saturday, May 23, surrounded by friends and family, including Paris and Nicky Hilton, Kyle Richards and her daughters, Farrah, Alexia and Portia, and Whitney and Chad Davis.

Kim entered a sober living facility in Los Angeles last month, following her arrest at the Beverly Hills Hotel, which resulted in a slew of charges against her, including public intoxication, resisting an officer and battery on an officer. 

Kim is facing two years behind bars and is due in court on June 11.
