Yolanda Foster has had a tough month after announcing her divorce from husband of four years, David Foster — but a new report claims he does not believe the Real Housewives of Beverly Hills star is telling the truth about her lyme disease.

“David and his family think Yolanda just loves the attention of being sick. They believe she’s exaggerating her condition. And they point out that she’s never gotten a legit diagnosis or a second or third opinion,” a source tells Us Weekly.

The source adds of the 66-year-old, “He didn’t understand why Yolanda wouldn’t leave The Real Housewives of Beverly Hills if she’s in so much pain and so tired. He’s famous and private and rich, so it was frustrating Yolanda wanted to do this show so badly.”

However, a second source insists the 51-year-old’s condition is NOT to be taken lightly, saying, “The sickness is very real and not fake. She’s being brave, and she’s a fighter. She did this season only to promote awareness of the disease.”

Yolanda and David revealed their plans to divorce earlier this month.
