During the sixth season of "The Real Housewives of Beverly Hills," the viewers could watch more of Yolanda Foster's battle with Lyme disease.

The former supermodel was diagnosed with a life-threatening illness a couple of years ago. According to International Business Times, Yolanda's diagnosis will be one of the major topics that they will discuss this season. Yolanda chose to undergo an unusual type of treatment to somehow make her feel better.

Yolanda later on invites Eileen Davidson and Lisa Rinna to come over her place. She then shows the girls her medicine cabinet which is filled with different types of medications and supplements.

In other news, Kyle Richards and Lisa Vanderpump went to Europe to unwind and relax. Lisa tells Kyle about Yolanda's situation. She told her that Yolanda had the crowns taken out of her teeth; which only got Kyle confused.

Also, Kim Richards will have another show in the near future. According to Design and Trend, Richards is currently shooting a show about popular mothers and daughters who have experienced hardships in the eye of the public and have undergone counseling to seek for help.

Erika Jayne will be introduced in the show next week. According to E! Online, Jayne and her husband are actually friends with Yolanda and David Foster.

"She brings a young energy and she has sex appeal," said by the site's source. "She's married but she loves to party and have fun," the source added.
