After discussing infidelity in marriages, Varun couldn’t help but roast Karan and asked him why he was so interested in the subject. KJo answered, “I’m interested in human behaviour in general.” Varun kept prodding, “Have you cheated in your relationship? Are you a cheater?” The host replied, “Am I cheating? I’ve to be in a relationship to cheat.” Varun said, “So you’re not saying that you are not in a relationship?” Karan answered, “You know I’m not, and you know I broke up.” Varun then said, “That’s what I wanted to hear.” The host added that Varun had been very supportive in that relationship. “I’m not cheating, because I have nothing to cheat on.”
