Talk show host Ellen DeGeneres teamed up with singer/songwriter Bruno Mars to play the ultimate prank on nurse Deborah who has been asked to help the pop-sensation in his dressing room. Ellen was in Bruno’s ear (literally) via an earpiece telling the artist everything to say. Mars told the nurse his throat was killing him after his Super Bowl Halftime performance and to his disbelief, she responded by saying “what do you do?” Ellen told the “Locked Out Of Heaven” star to say ”I haven’t swallowed since the Super Bowl,” along with some other ridiculous statements. Check out the full hilarious prank below!
