Luann de Lesseps Shuts Down 'Open' Relationship Talk In 'Real Housewives of New York' Premiere

In case you forgot, the ish hit the fan last season when Bethenny Frankel showed the Countess a photo of her then-fiance kissing another woman during their engagement. de Lesseps took her frustrations out on Bethenny herself for disclosing the information on camera. She also got into it with Ramona Singer, who called out Luann for breaking the "girl code" to date one of her exes.

Which brings us to tonight's premiere ...

While catching up with Dorinda Medley, de Lesseps explained why she'd be the only co-star invited to her wedding, expressing she wants it to be a "drama-free" affair. During the conversation, Luann also accused Ramona of calling one of Tom's exes "in the middle of the night" to get intel about him.

Singer definitely has some dirt on the duo, which she shared in her own conversation with Dorinda.

"She's the same way he is and they should just fess up and stop pretending they're something they're not," she said. "They like to have some open time with each other. She was just in Palm Beach, she was in the ladies room hitting on a guy who's 30." Her source: her girlfriend's mother, who heard it from his mother. "It's a small effing world, everyone talks," she added.

de Lesseps confronted Singer about it at the very end of the episode, when the two met for drinks.

"You've been doing a little Nancy Drew number. I don't want that," said the Countess. "Why would you go and call people that Tom knows and try to find out stuff about him and his past? That really bothers me."

"Tom and I are together, there's no open relationship. We are together," she added, adamantly.

"You should advise your husband-to-be it's a very small city," Singer responded. "He's doing things that are not good. It's gonna hit you in the face and I don't want to be there to pick you up."

Then she gave the worst toast ever: "I toast to your marriage, I hope you don't fall on your face with him. I'm afraid he's gonna hurt you. Here's to a fabulous marriage. I wish you all the happiness in the world."

The two still clinked glasses and de Lesseps ended the episode by stating, "This is going to be a really special year."
