Prince Harry just spoke out to reveal which member of the royal family intimidates him most.

In a trailer for the upcoming documentary series Queen of the World, Harry confessed that even he is intimidated by his grandmother, Queen Elizabeth! In the preview, Harry can be seen telling visitors to Buckingham Palace not to panic if they see the Queen.

“You guys have spent way more time in Buckingham Palace than I ever have and you’ve only been here two weeks! Have you bumped into the Queen yet?” Harry asked. “If you suddenly bump into her in the corridor, don’t panic. I know you will. We all do!”

Harry said this to a team of Caribbean hospitality professionals who were at the palace to take part in a new program.

This documentary series will cover the Queen’s role as head of the Commonwealth and how she is helping the younger members of the royal family connect with the 53 nations that are part of it. Over the past few months, the 92 year-old monarch has handed over a lot of her commonwealth duties onto Prince Harry and his new wife Meghan Markle.

Both Harry and Meghan will be in the documentary, which is set to air later this week, as will Prince Charles, Prince William, and Kate Middleton. In one of the most heartwarming scenes of the documentary, Meghan will even be reunited with the gorgeous Givenchy wedding dress that she wore during her wedding in May.

I can’t wait to watch this! Check out the trailer for this documentary below!
