Lisa Rinna and Andy Cohen's feud grew so intense that the Traitors season 4 star burned her former boss' memoir in her fireplace. The two were once close enough for Rinna to memorably lead a dance party full of Real Housewives stars at Cohen's baby shower in 2019. She even joined forces with Real Housewives of Beverly Hills nemesis Garcelle Beauvais to celebrate Cohen receiving a Hollywood Walk of Fame star in February 2022. However, Rinna's close relationship with Cohen sharply deteriorated after she announced that she was leaving RHOBH in 2023.
