RHOSLC: Mary Cosby Reveals Her True Feelings About Marrying Her Step-Grandfather

The first season of Real Housewives of Salt Lake City has been quite explosive. Housewife Mary Cosby, of course, has been at the center of a lot of the drama. Mary has been involved in some explosive fights with fellow housewife Jen Shah over the subject of her marriage — Mary married her late grandmother's husband, Bishop Robert C. Cosby, at her request — which has made for much fodder among the women.

The drama between Mary and Jen all began when Mary told Jen that she "smelled like hospital." At that time, Jen was frequently visiting her aunt, who was in the hospital because she had her legs amputated. Jen was rightfully offended by the comment. However, the pair had supposedly made up. Nope! When Meredith Marks, who Jen considers a close friend of hers, went to Mary's church for a service, Jen accused Meredith of not being a good friend. 

The drama peaked when all the women attended Whitney Rose's roaring 20s party. Jen went off on Meredith for hanging out with Mary. Meredith was over Jen's outburst and stated that she's done "engaging in the conversation," to which Jen screamed, "Are you serious? You're going to go with Mary? Who f***s her grandfather?" she exclaimed, per TooFab. "That's the truth. Oh, am I lying?" Of course, the whole club — and Mary — overheard. Then, on the Dec. 9, 2020, episode of RHOSLC, Mary Cosby shared how she really felt about marrying her step-grandfather. Keep reading to find out what she said.

Mary Cosby and Jen Shah got into another massive argument during Mary's Met Gala lunch, with each of the women throwing barbs at one another. Mary was hurt that Jen did not apologize for the comment Jen made about Mary's marriage at Whitney's party.

The next day, at home, Mary told her husband Robert, per People, "I don't need to explain to nobody — everyone knows our situation. You're not my blood grandfather." Mary then broke down in tears fearing that Jen was spreading lies about her marriage. "I think that's why they're doing it, because she's telling them all, 'Oh, she married her [grandfather]," she said. "Trying to make me a mockery."

Later in the episode, Mary met Heather Gay for dinner and further clarified things. Heather asked Mary, "So he's not your blood grandfather?" Mary became upset when responding, "No, that's incest. He is not my blood at all." She continued, "I did marry him. I didn't want to, Heather. I didn't want to. That's weird to me. But [my grandmother] really did want me to, so I obeyed her. I trusted every word."

Mary revealed that it took her two years to come to the decision to marry her husband. She said, "I had to be certain. I started to pray myself, I started to seek high help myself. When I did that, I felt peace with it, so I married him ... I chose what the man upstairs told me to do."

Bravo describes Mary Cosby as having a "penchant for God, couture, and only the finest champagne." She is also the "Pentecostal First Lady" of the Faith Temple Pentecostal Church who inherited her household's huge empire when she married her step-grandfather. According to reports, Mary's grandmother, Dr. Rosemary Redmon Cosby, was married to her second husband, Robert C. Cosby, for 22 years up until she passed away at the age of 65 in 1997. There have been allegations that Robert Cosby had something to do with his ex-wife's untimely death, according to Deseret News, but those claims are unproven.

Mary's grandmother, Rosemary, got exhumed when Mary's aunt, Rosalind Cazares, accused Robert of murder. Rosalind claimed that Robert had fought against having an autopsy conducted, even though it was the law in Florida. Robert said that exhuming his wife's body was like "putting salt on a wound." He said, It just burns and hurts." The findings revealed that Rosemary died of natural causes, according to the newspaper.

According to a report from The Salt Lake Tribune, Mary's husband Robert and Cazares have been involved in legal battles over the family fortune since Rosemary "Mama" Cosby's death. Cazares alleged Robert fraudulently diverted the assets after her mother's passing, and, in 2007, a 3rd District jury awarded the estate $1.2 million in damages and ordered Robert Cosby and Annie Johnson, business manager of the Faith Temple, to pay the money to Cazares. Talk about a wild ride.
