In the latest episode of "The Real Housewives of Beverly Hills" season 6, viewers finally got a peek at how Yolanda Foster's marriage crumbled.

In the previous episode, Yolanda invited her co-stars to attend a gala in New York where she will be honored by the Global Lyme Alliance. Erika Girardi, Kathryn Edwards, Kyle Richards, and Lisa Rinna agreed to come with her to the gala together with Yolanda's now-estranged spouse David Foster.

Before the gala ended, David was heard talking to one of his friends about his supposedly private marital problem with Yolanda.

David told his friend that he was he was starting to feel better but it still took a while before their problems wen away.

"I want your life to go back to the way it was when you first got together," David's friend told him. The music producer replied, "How's that going to happen?" The friend assured him that things would be better, but David seemed to be unsure about that.

But the public already knows the outcome of Yolanda and David's marital problems, since the couple called it quits in December 2015 and finalized their divorce in January this year.

Meanwhile, a source told Reality Tea that Yolanda refused to talk about what happened to their marriage during the shoot of the reunion episode of "The Real Housewives of Beverly Hills" season 6.

According to the source, the filming of the upcoming reunion episode was filled with a lot of drama, betrayed friends and apologies. But Yolanda kept mum about her problems at home.

"Overall, the reunion was rough. There were a few walk-offs," the source explained. "But it was not as vicious as last season."

The rest of the events that happened during the Global Lyme Alliance gala will be seen in the next episode of "The Real Housewives of Beverly Hills" season 6, airing on Tuesday, March 22, on Bravo.
