Yes she calls her sister. But awhile ago, long before she had OF and even her exclusive IG. She used to have regular lives and actually down talked onlyfans quite a bit. I have followed since she was just doing regular TT lives. Comments were made about Jazz then and she said they were actually cousins by blood but we're pretty much sisters otherwise. Also at that time, Jazz was not of age. I believe she's 2-3 years younger than Mariah. I actually still follow Mariah original IG before the countless others she made and made her real one private.
