'RHOBH' Season 6 Cast [RUMORS] Yolanda Foster Leaving After Lyme Disease Battle?

Are fans of The Real Housewives of Beverly Hills going to be seeing a whole new cast when the Bravo series returns for season 6? It might seem like that as there have been already two high profile exits with Brandi Glanville and Kim Richards' departures. Is Yolanda Foster the next blonde bombshell that will be exiting stage left? As fans know, David Foster's wife has been fighting a pretty draining battle with Lyme disease over the last couple of years. Rumors are that the illness may be forcing her to take a step back from reality TV.

It is being reported that Yolanda is getting better in regards to her condition, but that she might not want to return to the series because the ladies have started to question the validity of her sickness, according to Radar Online.

"[Foster's] very reluctant to return full time to the show because she feels that producers have pitted that ladies against her regarding the Lyme disease diagnosis," a source explained to the site. "Taylor Armstrong [and] other cast members are riled up about Yolanda's health, and question if the diagnosis is as bad as Yolanda says."

In related news, Yolanda took to her Instagram account last month to post that she has been feeling better following getting her breast implants removed.

"Turn a mess into a message...... We might have hit the jackpot by finding all this silicone from a 20 year old implant rupture through ultrasound mapping as shown in this selfie," the star captioned the image.

However, despite the claims from Radar that Foster is only "open to appearing on certain occasions," Glanville explained to ET that the star is definitely coming back next year, as she has already started filming.
