Ellen can get the guests on her show to do just about anything that's acceptable on daytime television. She constantly coerces stars into terrorizing unsuspecting bystanders, making them act out ridiculous charades playing "Heads Up", and she goes out of her way to frighten Taylor Swift every time she's on the show.
Madonna, who's on Ellen every day this week promoting her new album, Rebel Heart, shared the couch with Justin Bieber yesterday and Ellen had them play "Never Have I Ever" with her.
Madonna was the first to point out that some of the questions were a little tame, and that most were sexual. They were both good sports about it - though Ellen called Bieber out on one particular question he refused to change his answer on.
Ellen should have her guests share the couch more often - then maybe we'll get some of the priceless interactions that Graham Norton gets over the pond.
