To each his own. Karan invited them to the show but he didn't ask them to say what they did. Not that I think there was anything wrong in what they said. Some guests have chosen to take the diplomatic route where as others choose to have some fun. Ranbir and Imran were on the show before Sonam and Deepika and at the time Ranbir was more than happy to flaunt his casanova image. Not to mention Deepika had already given an interview before she even came on the show where she stated that Ranbir had cheated on her so these are all adults at the end of the day. Nobody force-fed them those answers.
