Prince George Adorably Silenced by Older Cousin at Buckingham Palace

Cousin rivalry is a thing, even for the Royals.

Prince William and Kate Middleton's oldest son, Prince George, got a little too mouthy for his cousin Savannah Phillips. So she told him to be quiet the only way a 7-year-old knows how ... by covering the future King's mouth in front of thousands of spectators.

The whole Royal Family was on the balcony of Buckingham Palace Saturday morning watching the "Trooping the Colour" ceremony, when planes flew overhead and distracted George. Apparently his older cousin thought his reaction was a bit overboard so she shut down the fun stat. Savannah is photographed telling George to "shhhh" before sticking her hand over his mouth!

The photos are adorable and the Duke of Cambridge's "dad" face in the background makes the whole thing even better! "Trooping the Colour" is a celebration honoring the Queen's birthday, which was actually months ago.

Prince Harry and Meghan Markle also made an appearance, their first event since they returned from their honeymoon!

They still have that honeymoon glow.
