During the show, while chatting with co-star Kristen Doute, the longtime reality star and waitress of SUR Restaurant was informed that her former boyfriend, Robert Parks-Valletta, who she dated throughout season six, had allegedly cheated on her by kissing another woman at a nightclub.

Along with a photo of herself and Robert Parks-Valletta, Scheana Marie wrote, "This is the most loyal man I’ve ever met in my entire life." She then added that during the night of the alleged cheating, Parks-Valletta never left her side.
