Mariah Carey was blindsided by news of the Las Vegas shooting during an interview on Good Morning Britain. Carey was supposed to be talking about her upcoming Christmas concert when cameras cut to her, lounged on a couch in front of a Christmas tree and host Piers Morgan asking for her reaction… Obviously the attack is a big story, but is this a time where you derail the show for a reaction (which was completely awkward by the way) or do you go on with the show as planned?
