The Platinum Jubilee celebrations honored Queen Elizabeth II's 70 years on the throne, but her great-grandson, Prince Louis, has been stealing the show.
Photos and video from Sunday's concluding festivities at Buckingham Palace show Louis making some more silly expressions while his mom, Catherine, Duchess of Cambridge, tries her best to handle it with grace.
The former Kate Middleton clearly has her hands full with this one.
On Thursday, when Louis, 4, appeared alongside the queen and the rest of his family, viewers could not help but notice the silly and energetic reactions he had to the Trooping the Colour parade, including the epic scream he appeared to let out during an Air Force flyby.
During Sunday's Platinum Pageant, which concludes the celebratory weekend, Louis stood on his seat while biting his lower lip.
In another photo from the ceremony, Louis covers his eyes with his hands while his mom speaks to him. Twitter has been taken with Louis' very real reactions to the celebrations, and fans immediately called out his "vibes" at the pageant.
In the photos that show Louis with his more staid siblings, he appears to be yawning. In another pic, he holds a cushion up to his mom while a man in a neighboring seat looks amused by the shenanigans.
In perhaps the best pic from the event, Louis holds a hand up to his nose and sticks his tongue out at his mother, while Kate looks like she's scolding him — a situation any parent can certainly sympathize with!
In another photo, Louis entertains himself by reading the pageant's program, while his sister Charlotte smilingly watches the ceremony.
On a livestream of the Jubilee Pageant, Prince Louis appeared to leave the area shortly before returning and sitting on the lap of his grandfather, Prince Charles.
Later, he moved to sit back between his mother and sister, where the funny faces continued as he danced along with the pageant performers.
Shortly after the pageant ended, Prince Louis, his parents and his siblings appeared with Queen Elizabeth II in a surprise appearance on the balcony of Buckingham Palace.
