So Prince Harry and first lady Michelle Obama are old friends.
They've recently joined forces to bring the Invictus Games — a Paralympics-style competition in which wounded or injured service members and veterans from different countries compete against each other — to the United States.
Prince Harry, an army veteran who served two tours in Afghanistan, created the Invictus Games in 2014 to "harness the power of sport to inspire recovery, support rehabilitation, and generate a wider understanding and respect for those who serve their country."
The United States won the bid to host the second Invictus Games, which will be held at the ESPN Wide World of Sports at Walt Disney World from May 8–12.
