Yolanda Hadid and David Foster split in December 2015 after being married for four years. However, the couple’s problem was not that evident when the Real Housewives of Beverly Hills (RHOBH) went to New York City for the Global Lyme Alliance’s Uniting for Lyme-Free World event.

In the show’s episode on Tuesday night, the RHOBH cast went to NYC to support Hadid, 52, who was given recognition for helping spread awareness about the Lyme disease. The event took place in October last year.

One preview clip of the show showed Foster, 66, talking to his friend, Tom about the status of his relationship with Hadid. They were not wearing microphones at the time, and did not know that they were being filmed.

Tom asks Foster if he is feeling better, and the Canadian composer replied, “A little, yeah. It’s been a stretch.”

His friend then tells him, “I want your life to go back to the way it was when you first got together.”

However, a pessimistic David Foster responds, “How’s that going to happen?” Tom wants to reassure his friend, but the musician just sounded weak and defeated.

The tone in Foster’s remark may have given away what was going to happen a few months later.

Ever since his wife contracted Lyme disease, which she got from a tick bite, their marriage had never been the same.

Even Hadid admitted that her illness was a pretty big blow in their relationship.

“He married a woman that was a social butterfly, always out, and doing and doing … and then all of a sudden, I got sick,” Yolanda says in a confessional.
