David Foster has joined the ranks of those accusing Yolanda of faking her Lyme disease, RadarOnline.com has learned.
According to an insider, "David is telling friends he believes she was cured of it long ago, but she's been playing up ongoing symptoms because she enjoys the attention."
Yolanda was first diagnosed with Lyme disease just a year after the couple got married in 2011.
At the time, "There was no doubt Yolanda was struggling and David was there to support her," the source said. "In the beginning, David went with her to all of her doctor's appointments, including the overseas trips for other treatment."
As time went on, however, "Yolanda just seemed to really enjoy all of the attention she was getting," the source claimed.
"Her oldest daughter, Gigi was becoming a very successful model, and it seemed hard for Yolanda, a former model herself, to watch her child get so much attention."
"Getting older seems to have been very hard for Yolanda," the source said. "Now, it looks like she isn't ready to give up the role of sick patient."
"In fact, Yolanda's doctors in L.A. recently insisted she cut back on the trips abroad for medical care, believing it was making her symptoms worse, but she refused," the source said.
"And anyone that saw RHOBH this week knows that Yolanda's medical closet is stocked from top to bottom with prescriptions, injections and supplements. People close to her think that all of that stuff is just making her feel worse, but she won't give them up," a source told Radar.
In addition, the source added, "Yolanda recently admitted that she has been getting weekly colonics while battling the disease. David begged her to stop doing that because her doctors believed that was also hurting her, but she refused that too."
Yolanda, however, insists that her disease struggle is all too real, and has hinted that differences with David surrounding the issue torpedoed her marriage.
During Tuesday's juicy segment on Watch What Happens Live, the 51-year-old dished the dirt on what really ended her relationship –– and she didn't hold back.
"Well, chronic long-term illness is extremely challenging," she said, implying that her Lyme disease diagnosis caused marital issues. "Not only for the person who is sick but also for the caregiver. It for sure changed the dynamic of the relationship."
Meanwhile, "David just hates being portrayed as the bad guy in the relationship, and that he wasn't there for her. It's just not true," the insider added.
