'RHOBH' Kim Richards Feud with Sister Kyle Over? Daughter's Wedding Instagram [PHOTO] Shows Possible Amends

Kim Richards might have had reason to celebrate over the weekend, as it was her daughter Brooke Brinson's wedding, but was it a good idea for the Real Housewives of Beverly Hills star to check herself out of rehab for the occasion? Well, it certainly seems that way, as the celebration was a family affair that included the whole gang. Even Kyle Richards joined the festivities, making us think that her and Kim are on good terms now, or at least able to put their differences aside long enough to be civil to one another for a day.

According to People, Kim's daughter got married over the weekend at One & Only Palmilla in Cabo San Lucas, Mexico, where she said "I do" for the second time to hubby Thayer Wiederhorn. The couple's first wedding was documented for the fifth season of RHOBH, but the pair decided to renew their vows less than 10 months later in their dream beach wedding.

While Kim's latest antics and run-ins with the law might have deterred some from checking out of rehab to watch their daughter get married for a second time, it doesn't seem that Kim was going to let anything stop her.

"It's always been Brooke's dream to get married in Cabo so this second wedding is really important to her," an insider close to Kim's family explained to the site, adding, that despite her rehab treatment that Kim, "wouldn't miss," the wedding for the world.

Another member of the family who didn't miss the wedding for the world was Kyle, who many were speculating wouldn't be attending because of her falling out with her sister. However, the starlet took to her Instagram account to post a picture of herself hanging out with Kim and the bridesmaids, which included some of Kyle's daughters, as well as Kim's nieces Nicky and Paris Hilton.

In the caption, Kyle simply wrote, "Wedding day."
