Block 5 premiered not just one, but two A-list celebrity videos during the last hour of the block. U.S. Figure Skater Mirai Nagasu told dancers that although she is a Olympic medalist, she "could never dance for 30 hours straight." Actress and dancer Alyson Stoner touched dancers' hearts and thanked them for "letting us witness something beautiful."

  1. She is the third woman in the world to ever land a triple axel at the 2018 Olympics. It was during the free skate in the team event, and she became the first American female figure skate to ever do so.
  2. Nagasu was a dual citizen of Japan. Her parents are Japanese immigrants, but had to choose between her Japanese citizenship and U.S. one before her 22nd birthday.
  3. In 2008, Nagasu became the youngest woman to win the U.S. senior ladies' title. She is the second-youngest woman in history to win the title.
  1. Stoner was the voice of Isabella in the Disney Channel animated series Phineas and Ferb.  You might remember her as the character who'd ask Phineas, "Whatcha doin'?", which Stoner actually came up with herself.
  2. Stoner has worked as a background dancer in a few of Missy Elliott's, OutKast's and Eminem's music videos. She currently teaches hip hop classes in LA, and is the youngest person to teach a master class at the Millennium Dance Complex.
