Real Housewives of New York City fans were shocked by the news that Carole Radziwill is returning to the show - and so was her former costar Dorinda Medley. "I'm surprised I knew nothing about it, and we're quite close," Dorinda, 61, said during the Monday, March 2, episode of her Reality Checked show on SiriusXM. "So she kept it very - her cards very close to her chest." Bravo announced earlier on Monday that Carole, 62, will be returning to RHONY as a "friend" of the Housewives for season 16 alongside Jessel Taank, Erin Lichy and Sai De Silva.
