“The Real Housewives of Salt Lake City” star Mary Cosby and the church she runs with her husband, Robert Cosby Sr., are back in the spotlight … this time accused of being a full-blown cult, according to a bombshell new TLC doc.
TMZ’s got your first look at the wild new trailer — the three-parter dives deep into Mary’s eyebrow-raising marriage to her step-grandfather, Robert Cosby Sr., and the misconduct claims that dragged Faith Temple Pentecostal Church into one seriously controversial new chapter.
