Mary Cosby was only 22 when she married her step-grandfather Robert Cosby Sr., now 62.
The Real Housewives of Salt Lake City cast member said she told Robert Sr. she was on her period to avoid having marital sex with him on their wedding night.
"I'm not gonna lie it was all bizarre. Thank goodness I was on my period at the time and the period lasted about two weeks."
Mary said he repeatedly asked if she was still on her period. She said she prayed on it before eventually consummating their marriage on the 28th day.
Mary's grandmother, Rosemary "Mama" Cosby (pictured with Robert), pre-ordained that Mary would inherit her estate -- including the Faith Temple Pentecostal Church, other churches, homes, restaurants, money, and her second husband, Robert Sr.
When Mama Cosby passed, Mary inherited everything that her mother thought she should've received as her mother’s closest next of kin. Mary's inheritance drove a wedge between her and her mother to this day.
"I was actually 22 when I got married. It split our church. My mom felt like she was the one who should have had all of it and the church," Mary said.
Mary said she was 19 when she last spoke with her mother - her best friend at the time.
As for consummating her marriage on the 28th day, Mary said, "It worked out so good. Like, it couldn't have been better."
Bravo posted a sneak peek of next week's episode 3 of Real Housewives of Salt Lake City on YouTube.
Whitney Rose plans a roaring 20s party inside an antique store. Heather Gay hosts a baby shower for five of her young, Mormon, pregnant employees. She plans to surprise them with five Range Rover baby cars (all 5 employees are having boys); Meredith Marks and Mary Cosby grow closer, and Jen Shah acts inappropriately at a nighttime gathering.
Jen (right) gives Heather a pep talk after Heather breaks down in tears while discussing the end of her marriage and not achieving the "perfect family."
Viewers are jealous of Jen's incredible lacefront wig, which looks natural like it's growing out of her scalp. Beyonce should holler at Jen's wigmaker. Beyonce has never worn a lacefront wig that looked authentic or genuine in her life.
Mary is annoyed because her only son, 17-year-old Robert Cosby Jr., is in a serious relationship with a girl at his high school - and Mary is desperate to break them up by sending him away to a boarding school in Los Angeles.
"I feel like it isn't necessary," says Robert, who adds that he will be lonely without his girlfriend there. Meanwhile, Robert looks to his father, Robert Cosby Sr., for a little help and support. But Robert Sr. doesn't say a word in his son's defense.
Brooks, Meredith's overbearing, effeminate, 21-year-old son forbids his mom from having a sleepover with Jen after Jen inadvertently exposed her lady parts to him and his sister Chloe.
"That's definitely not happening," he tells Meredith in an authoritarian way. "You're a CEO," he tells her, "You're never gonna have time for a sleepover in your life."
Real Housewives of Salt Lake City cast member Heather Gay is being praised by the LGBT+ community for her response to a social media troll who called her a male-to-female transgender.
Heather, a divorced mother of three girls, had the perfect response when a cheeky social media user asked her: "Could you share more about your transition from male to female? You're going to inspire SO MANY PEOPLE!"
Heather politely responded, "I'm happy to be an advocate for the transgender community if it helps! I'm not transgender but I don't consider it an insult to be called trans either. Let's bring as much awareness as possible to the LGBTQ community! I'm here for it."
Heather is the co-owner of Beauty Lab + Laser, a specialty cosmetics practice that she says is worth $20 million.
In a recent interview with Page Six, Heather said she aspired to be a ghey icon.
"Oh my gosh, I've been praying my whole life to become a ghey icon. If the gheys will take me I will carry the badge of honor."
Heather was born into the Mormon religion and married a member of the influential Gay family, who she says inherited billions from Howard Hughes.
Her divorce was finalized in 2015.
Bravo's Real Housewives of Salt Lake City premiered last night to positive reviews. The cast members introduced their families, including Jen Shah who introduced her husband, Sharrieff Shah and their 2 sons.
Jen's husband is a football coach at the University of Utah. Jen, who was born in Hawaii, moved to Utah when she was 7. She says she converted from Mormonism to Islam after meeting and marrying her husband.
Jen says she is Tongan "and a little bit of Chinese." But in Utah, she says, "I'm Black, because people don't know any better."
Sharrieff, 49, explained how he and his wife met in college. "We had a class together. I saw her, my heart stops immediately," he recalled.
"I walk up to her, is that seat taken. She looks at me like, 'There's nobody there, I guess not.' That's how we met."
Jen said their marriage isn’t perfect. She sees him when he leaves home at 5 a.m. and when he returns at midnight. "We basically have to FaceTime a lot. It's kind of like a FaceTime marriage."
Mary Cosby explained her "arranged marriage" to her 62-year-old husband, Robert Cosby Sr., on the series premiere of Real Housewives of Salt Lake City.
As you know, Mary, 47, inherited her family's empire of churches when she married her late grandmother's husband, who is her step-grandfather.
The Pentecostal First Lady, who has been married to Robert for 21 years, explained that her marriage was ordained in her grandmother's will.
"It was kind of in my grandmother's will for us to be married," Mary said.
Robert added, "She said if anything happens to me - Bobby - I want you to marry one of my girls because they'll look out for you."
