AceShowbiz - Before Prince Harry has a reported strained relationship with his family, he enlisted the help of his grandmother to trade a friendly banter with the Obamas. In response to the then-U.S. President and his wife's message for Invictus Games, the Queen teamed up with her grandson for a funny video in which they watched a video of the Obamas, who said, "Remember when you told us to bring it at the Invictus Games? Careful what you wish for." After watching the video, the Queen said, "Oh really, please," and then Prince Harry stared at the camera and said, "Boom."
