Prince Harry can't hide his excitement at the news of a new niece or nephew on the way – or resist the chance to poke fun at Prince William.
Harry was smiling at an Invictus Games training session for athletes when he joked, "I can't wait to see my brother suffer more" with the arrival of a second child.
And if the Duke and Duchess have a girl this time, Harry quipped that he would "love to see him try and cope with that."
After welcoming wounded and injured soldiers to compete in the sports event that he helped to create, Harry, 29, continued to comment on the pregnancy news, this time in a more serious tone.
"I hope the two of them have the opportunity to go through the process again with a little bit of peace and quiet," he said, adding that sister-in-law Kate was feeling "pretty poorly" from morning sickness, but "doing the best she can."
When asked whether he could give the new baby any advice or "strategy" on being a younger sibling, he said: "There's never a strategy. I think George will be over the moon. He will be thrilled having another small younger brother or sister."
And when it was mentioned to Harry that the new addition to the royal family would further reduce his own chances of being king, he laughed and replied, "Great!"
