The RHOSLC star has an estimated net worth of $5 million and she'd made it clear that it's all thanks to her grandmother. While both she and her hubby, Robert St. claim that Mary's grandmother requested this to happen, the star revealed during the second part of the reunion that her grandmother never put any of this in writing.

This took a toll on Mary's relationship with her mother and extended family members, as she stepped into her grandmother's place and gained access to the entire family fortune. Now, Mary resides as the First Lady of her Pentecostal church, which received some questions after it was rumored that Mary takes money from her congregation.

It's clear the star has a lot of money, but viewers are questioning her methods as to how she got there. Mary put just that to rest during the reunion, claiming that all that should matter is her happiness and now how she came to be so wealthy.
