VIDEO: DAVID FOSTER Thinks Yolanda is Exaggerating Disease? While Yolanda says she has spent a year in bed, a friend of David’s told US Weekly, David thinks she’s exaggerating her condition and thinks she just loves the attention of being sick. They point out she’s never gotten a legit diagnosis. Another source says David doesn’t understand why Yolanda wouldn’t leave Real Housewives of Beverly Hills if she’s so ill. But even though he’s skeptical, David has still shelled out nearly 5 million dollars for her treatment.
