This was a surprise to everyone, including the star herself, but producer Andy Cohen recently explained why he stayed mum when it came to her cameo.

"Jill is a Yenta! She likes to talk, and I didn't want her telling anyone that she was in the super tease," he told AOL. "I think it was better that way, actually. She e-mailed me that morning, and she was like, 'My phone is blowing up! I had no idea!' It was great. I just wanted it to come out [in the trailer]."

Mrs. Bobby Zarin is also over the moon about her triumphant return.

"The secret is out! I do pop in this season for a cameo on Real Housewives of New York! It was a thrill to film again and reminded me of how much fun we had back in the day. Thank you for all your love and support. Bobby and I had a great time even if only for a moment. #realhousewivesofnewyork #bravotv #realhousewivesofnewyorkcity," she wrote on Instagram last month.
