The ladies of Bravo's "The Real Housewives of Beverly Hills" are off to Dubai, United Arab Emirates, but they're anything but relaxed. Shortly after arriving at their lavish accommodations, the ladies get into a conversation about Yolanda Foster's Lyme disease, which creates quite a stir.

Kyle Richards rounds up her "RHOBH" co-stars for the trip of a lifetime after returning to Beverly Hills, California, from the Global Lyme Alliance Gala in New York City. Everyone but Yolanda is able to attend and seems eager to explore a new culture. After a lengthy flight, the ladies land in the City of Gold and sort out their sleeping arrangements. They settle in before gathering for dinner, which is generally where all "Housewives" sit-downs go awry. After the meal, the conversation shifts to Yolanda, who was not able to attend due to her ailment. From there, the ladies begin discussing the Global Lyme Alliance Gala, sharing the many touching moments between Yolanda and her children during the event. Erika Girardi expresses to Lisa Rinna — the biggest Yolanda doubter in the bunch — her wish that she could have been there, telling her that she may have gotten a lot of answers from being there. Lisa R. agrees, but says that she still has questions about what's going on with Yolanda. At this point Eileen Davidson, who chatted with Lisa R. about Yolanda in a previous episode, chimes in to tell her gal pal that even she is unsure why she still has questions.

Lisa R. attempts to explain herself but is met with contention from her co-stars. She claims that she doesn't necessarily doubt that Yolanda has Lyme Disease but believes that she uses it to her advantage. She continues, bringing up Erika's dinner party once more. She claims that it was wrong for Yolanda to skip the dinner and looks to Erika to get her feelings on the situation. Erika reiterates that she spoke to Yolanda before the party and told her not to come if she wasn't feeling well.

Meanwhile, at home, Yolanda is throwing a little shade of her own. The "RHOBH" star meets with Brandi Glanville — former housewife and known pot-stirrer — to discuss the ongoing drama. She shares with Brandi what Lisa R.'s been saying, which enrages her. In a one-on-one confessional Brandi, tells Lisa R. to "get a f---ing life, and eat some food."

The drama continues during episode 18 of "RHOBH." Tune in Tuesday at 9 p.m. EDT.
