Kelly Bensimon isn't looking to replicate her infamous meltdown in St. John.
The reason? "I cannot go on a trip with Ramona [Singer]," she explains. "It's hard for me to be in a room with her. I'm too sensitive."
"You guys are amazing and I don't want to put myself in a situation where I have to remove myself," Bensimon adds, referencing her early exit from the cast's St. John vacation in season 3.
De Lesseps, 46, can't understand why Singer's presence would prohibit Bensimon from having a good time. "This trip is going to be fantastic," she presses. "Why are you letting Ramona interfere with this trip? It's not seven days of her -- it's seven days of us!"
