Kathy Hilton has revealed that she was tricked by an AI-generated scam promoting a diet she falsely believed was endorsed by celebrities like Oprah Winfrey, Michelle Obama, and Kelly Clarkson. The scam, which affected her health, prompted her to tell her fellow cast members of the Bravo show that the diet was so restrictive that she could not fit into anything. The news comes as Oprah's team urges viewers to take extra caution before providing their personal information or purchasing any products.
