Season 5

As any true New Yorker knows, a shifting social circle requires fresh blood, and the arrival of downtown princess Carole Radziwill, shapewear mogul Heather Thomson, and phobia-ridden Aviva Drescher instantly shakes up the Upper East Side. While Luann de Lesseps gracefully dodges parenting rumors, a wildly defensive Ramona Singer clashes immediately with the boisterous new additions. The ultimate test of this fragile new sisterhood comes during a luxurious getaway to St. Barth's, where Ramona and Sonja’s uninhibited partying collides head-on with Aviva’s demands for basic respectability, creating an unbridgeable island divide.
