Real Housewives of Beverly Hills: Kim Richards back in rehab after meltdown; will she return for season 6?

Real Housewives of Beverly Hills star Kim Richards is back in rehab in Los Angeles.

According to reports, the troubled reality star checked in at the centre after a week-long break, as she wanted to attend her daughter Brooke's wedding in Mexico.

E! News reported that Richards was doing okay in rehab. "She's doing ok, a lot better than she had been," a source told the website.

However, the 50-year-old allegedly caused a scene at her daughter's wedding, after getting intoxicated and "fought with everyone", leading her sober coach to ditch the vacation.

The website stated that Richards had been at a treatment centre for a few days, and the facility was different from the one she initially checked into, following her arrest back in April.

A Bravo TV source told Radar Online, "The network was told that Kim checked back into rehab on Monday, as they requested her to do."

"However, Kim still refuses to speak to any of her bosses on the show directly and they had to find out through family members," added the source.

But Richards' recent bad behavior may not push the Bravo producers to fire her just as yet, the insider insisted.

"Although they are not 100 percent certain yet about her future on Real Housewives of Beverly Hills, if she checked back into a treatment center voluntarily, she will most likely not be fired from the show, " the insider revealed.

So, fans may indeed get to see Richards when Real Housewives of Beverly Hills season 6 returns on Bravo TV.

In April, the RHOBH star was arrested at the Beverly Hills Hotel after she reportedly got drunk. Richards appeared to have "had too much to drink and was disturbing some of the other patrons" in the hotel's restaurant.
