Mary didn't give any evidence about her claims of Gay's racism, but Gay claimed Mary's blocking was over a petty argument.
The RHOSLC city star said, 'Basically, I told her to f*** off and she blocked me,' during an interview with Bravo Insider, before letting out a laugh.
A source claimed to Page Six that the online conflict between the two women wasn't related to anything that had happened while filming their series.
Despite accusing Gay of being a racist, Cosby has had her own race-related scandals.
