In an explosive preview clip from this week's reunion episode, Lisa Hochstein is asked why she thinks newlyweds Joanna Krupa and Romain Zago don't have sex.
"I just think they've been together for a very long time, and Joanna can sometimes be a little emasculating," Lisa says.
Then, Adriana chimes in with her own explanation. "Maybe he's gay," Adriana offers.
"Yeah, 'cause Romain really looks it, Adriana," Joanna replies, although that comment baffles host Andy Cohen.
Then, the gloves come off, and the ladies get vicious. "You are a cold-hearted human," Joanna tells Adrianna, to which Adrianna replies, "You are a homewrecker, everybody knows it. Don't try to deny it now."
