When Kelly Bensimon decides to confront Ramona Singer on the May 5 episode of The Real Housewives of New York City, she enlists the help of costars Sonja Morgan, 47, Jill Zarin, 47, and LuAnn de Lesseps, 45.

"I'm having lunch with Ramona because I'm really concerned with her behavior," Kelly explains.

Given her history with Singer, 54, Morgan suggests Bensimon engage in a role-playing exercise. "What's your concern, darling?" Morgan -- as Singer -- asks.

"I got a text from you at 1:30 in the morning on a Saturday," Bensimon says.

"Oh, well excuse me! A drunk text? At least I thought of you," Morgan says while still in character. "I could have texted anyone, darling."

"But your text was in response to me not coming to your party," Bensimon counters.

"What party? I've had three this week. Which one? Can you tell me?" Morgan responds. "I drink pinot grigio by the mile!"

The Real Housewives of New York City airs Thursday at 10 p.m. EST on Bravo.
