When Mariah appeared on Watch What Happens Live with Andy Cohen on Sunday night, she commented on the rumor about Quad and her brother-in-law, which Quad had said was not true at the reunion.
Quad mentioned the allegations at the reunion as the ladies discussed the topic of the so-called receipts Mariah said she had that Dr. Heavenly Kimes' husband, Dr. Damon Kimes, had been unfaithful. Quad called Mariah a "liar" and accused her of having something to do with a blog reporting the rumors about her.
Mariah denied having anything to do with the allegations getting out there during the reunion and said on WWHL that she never would have made it public. "I would never bring that up. That's my family," she said.
Quad said during the reunion that the rumor was a lie. "She doesn't care who she hurts," she said of Mariah. "If it's to destroy me, she will do it by all means necessary."
There are more surprises on the way in an all-new episode of Married to Medicine coming up on Sunday at 9/8c. Catch a sneak peek, below.
