News Meet the Youngest Princess in the Entire World By Alexandra Whittaker Updated on March 9, 2018 @ 02:45PM Pin Share Tweet Email There's a new royal in the world, and she's already making waves on social media. Swedish Princess Madeleine and her husband Chris O'Neill welcomed their third child—a baby girl—on Friday, and the Swedish Royal Court's Instagram account immediately posted a photo. The new princess is officially the youngest princess in the world and arrived March 9 at 12:41 a.m. at Danderyd Hospital in Stockholm. The unnamed baby joins her siblings, 4-year-old Princess Leonore and 2-year-old Prince Nicolas, in the family. Her grandparents are King Carl XVI Gustaf and Queen Silvia. In her very first photo, she lies on a white blanket in a cute pink and white outfit while resting. “Leonore and Nicolas have their long-awaited sibling,” her dad O'Neill said in a statement from the palace, according to People. “They can’t wait to meet their new baby sister.” Princess Madeleine's youngest child is now part of Europe's largest royal family. Princess Madeleine is the youngest daughter of the King and Queen, and her new daughter is their seventh grandchild in the notoriously large Swedish royal family.

The new princess isn't the only little royal to be born this year, though. In yet another parallel to the Swedish family of royals, Kate Middleton and Prince William are expecting their third child as well. Middleton is due in April, and the new baby will join big siblings Prince George and Princess Charlotte in the family. Update: After being introduced to the world through Instagram, Princess Madeleine's youngest daughter now has a name. Princess Madeleine announced on Monday that her newborn daughter's name is Adrienne Josephine Alice.
