Kyle Richards shares bikini photos amid marital speculation

Kyle Richards, 56, recently shared new bikini photos on Instagram, showcasing her toned body. The images feature her in a hunter green string bikini, which she used to promote the latest episode of "Real Housewives of Beverly Hills." During a trip to Saint Lucia, the topic of her estranged husband, Mauricio Umansky, 54, dating women came up. Reports surfaced of Umansky kissing 34-year-old Nikita Kahn, prompting discussions among the cast about his romantic life. Kahn is a Ukrainian-American actress and model. At a group dinner, Kyle and her co-star Bozoma St. John talked about Mauricio's new relationships. Boz revealed she had seen him with Nikita at a venue shortly after their discussion. Kyle clarified that it was just "a girl" and not "his girl." Other cast members, including Garcelle Beauvais and Kathy Hilton, felt that it seemed serious. The conversation also turned to Kyle's own life. Beauvais expressed confusion over Kyle's connection with singer Morgan Wade. Kyle asserted there was no romantic situation between them and noted that her public appearances were just part of her work. Meanwhile, Mauricio has also been spotted with singer Anitta, though they claim to be just friends. Kyle and Mauricio are currently separated but have not filed for divorce. "The Real Housewives of Beverly Hills" airs on Tuesdays on Bravo.
