The TLC docuseries "The Cult of the Real Housewife," which premiered this week, is investigating "The Real Housewives of Salt Lake City" star Mary Cosby and allegations of cult behavior surrounding her church, Faith Temple Pentecostal Church, in Salt Lake City. The three-episode exposé features first-hand accounts from ex-congregants and family members, delving into Cosby's childhood and her marriage to her step-grandfather, Robert Cosby Sr., according to TLC.

The documentary explores accusations that Cosby is a cult leader, a rumor that has circulated since her debut on "RHOSLC." The series aims to uncover the truth behind these claims, presenting interviews and evidence gathered by investigative journalists. The series also examines the financial dealings of Faith Temple Pentecostal Church, questioning how the church's funds are managed and whether they benefit the Cosby family disproportionately.

Cosby's marriage to Robert Cosby Sr. has been a source of controversy since it was revealed on "RHOSLC." The marriage occurred after the death of her grandmother, who reportedly stipulated in her will that Mary would inherit her empire, including the church, only if she married Robert Sr. The documentary explores the circumstances surrounding the marriage and its impact on the family and the church community.

"The Cult of the Real Housewife" is expected to generate significant buzz, given the popularity of "The Real Housewives" franchise and the controversial nature of the allegations against Cosby. Industry insiders predict the docuseries will draw a large audience, further fueling the debate surrounding Cosby and her church. The cultural impact of the series remains to be seen, but it is likely to spark conversations about religion, power, and reality television.
