Kim Richards Back to Filming 'Real Housewives of Beverly Hills'

While she will not be returning as a regular cast member, the troubled reality star has started filming cameos with her castmates for season six.

Despite the speculation that she would not be returning to the Real Housewives of Beverly Hills, Kim Richards has started filming season six with her castmates.

Richards was spotted in Beverly Hills Park with Yolanda Foster and Brandi Glanville on Friday.

The three were being filmed having a picnic lunch. After the meal, Richards carried a blanket out of the park, while Glanville had shopping bags in tow and Foster held onto a picnic basket.

A source close to Richards tells ET that producers called the 51-year-old reality star back to be a part of a few episodes.

“Everyone sees the progress she has been making and everyone was happy to have her back!” the source said.

Oddly, Glanville was sporting a blue tank top that said, "It's not fun to be sober," despite the fact that Richards has a history of battling substance abuse issues.

It isn’t a complete surprise that Richards is filming for RHOBH. While ET learned in June that she would not be returning as a full-time cast member, there was word that she would be making a cameo or two in the upcoming season, and she appeared in the recently released season six trailer.

This has not been an easy year for Richards, who entered rehab for the fourth time in April after she was arrested at the Beverly Hills Hotel for public intoxication. Then in August, she was arrested for shoplifting at a Target in Van Nuys, California.

Shortly after the shoplifting incident, a source told ET that Richards had spent months battling alcohol and substance abuse issues and was “getting the help and support she needs.”

That seems to include taking advantage of the gorgeous Los Angeles weather as of late. On Thursday, she shared a photo of a lovely SoCal sunset with her 293,000 Instagram followers.

Last month, Richards moved into a one-bedroom, one-bath condo in Westwood, California, just one neighborhood over from Beverly Hills.

At the time of her move, a source told ET that Richards is doing much better, saying, "She’s focused, she’s sober, she’s happy.”
