“Real Housewives of Beverly Hills” star Kim Richards had to put rehab on hold over the weekend -- because her daughter Brooke Brinson got married (again)! The 50-year-old Bravo reality-television star flew to Cabo, Mexico, to attend her daughter’s “dream” wedding.

According to E Online, Kim Richards has been in rehab for close to a month. She reportedly checked in for substance-abuse treatment at a facility in Malibu, California, after her April 16 arrest and subsequent interview with Dr. Phil. The reality-TV star, who has been struggling with her sobriety, allegedly refused treatment at first. However, TMZ reported at the time that she changed her mind after “consulting with family.”

For those confused about the nuptials, Brooke initially got married last August in Beverly Hills, California. The nuptials at the home of Paris Hilton’s mom, Kathy Hilton, were shown during a December 2014 episode of Bravo’s “Real Housewives of Beverly Hills.” Brooke and fiance Thayer Wiederhorn decided to wed after learning that her father’s cancer had worsened. Her father, Kim Richards’ ex-husband Monty Brinson, was able to walk her down the aisle.

Monty revealed on Instagram that the Cabo ceremony Saturday was his daughter’s “dream wedding.” Unfortunately, he was unable to attend because of his battle with cancer.

“My daughter is getting married on Saturday, her dream wedding on the beaches of Cabo,” Monty captioned a photograph of himself with Brooke on her August 2014 wedding day. “Everyone left this morning but unfortunately for me for health reasons I wasn’t able to attend, but I’ve still been blessed that I was able to walk her down the aisle in August. As everyone knows last May I was given a few months to live, but guess what I’m a fighter and it’s a year later, still not giving up.”

While Monty was unable to attend, photos show Kim Richards with sister and fellow “RHOBH” cast member Kyle Richards. Paris Hilton, Nicky Hilton and Faye Resnick were also in attendance.
