Kim Richards has been spotted filming a scene for season 6 of "The Real Housewives of Beverly Hills." According to Entertainment Tonight, the former child star was seen in Beverly Hills Park with Yolanda Foster and Brandi Glanville on Friday, Nov. 6.

The three ladies were filmed while they enjoyed a picnic lunch. Kim wore a vest over a white long sleeved shirt and jeans, while Yolanda wore a grey sweat shirt and matching pants. Brandi was dressed in a grey tank top and black jeans.

A source close to Kim told ET that producers called her to be a part of a few episodes.

"Everyone sees the progress she's been making and everyone was happy to have her back!" said the source.

Earlier this year, it was reported that the 51-year-old was not returning to the Bravo show so she could focus on her health and on getting sober. Kim went into a treatment facility after she was arrested for public intoxication at the Beverly Hills Hotel in April. In August, she was arrested for shoplifting at a Target in Van Nuys, California.

Last month, it was reported that the reality star moved into a one-bedroom condo in Westwood, California, and a source told ET at the time that Kim was doing well.

"She's focused, she's sober, she's happy," said the source.

Meanwhile, Glanville's return to the show was also a big surprise for fans of the former model. The 42-year-old announced last June that she was leaving the show, but a source from Us Weekly said that she was brought back "to bring in some drama and liven things up." Glanville famously feuded with Lisa Rinna, Lisa Vanderpump, and Kyle Richards last season, and it was reported that her constant fighting with the ladies led to her exit earlier this year.

"The Real Housewives of Beverly Hills" season 6 premieres on Dec. 1 at 9 p.m. on Bravo.
