In her cast bio, Heather says she’s “Mormon-ish,” and in the Bravo Insider preview for the show, co-star Lisa Barlow describes herself as “Mormon 2.0.”

Fellow RHOSLC star Whitney Rose, meanwhile, says in the clip that she “grew up Molly Mormon” — a nickname for a stereotypical female member of the Church of Jesus Christ of Latter-day Saints — but another preview reveals that Whitney, Heather’s cousin, was excommunicated from the church.

The other three Housewives aren’t Mormon either. Mary Cosby is Pentecostal, Meredith Marks says she’s “proud to be Jewish” but “not a very religious person,” and Jen Shah tells viewers she was raised Mormon but converted to Islam.
