Merida, the lead character from Pixar's animated feature Brave, will be "coronated" as an official Disney Princess at Walt Disney World's Magic Kingdom on May 11, 2013.
Merida will be joined by the 10 existing Disney Princesses (Ariel, Aurora, Belle, Cinderella, Jasmine, Mulan, Pocohontas, Rapunzel, Snow White and Tiana) for a special ceremony to mark the occasion. It will be held at 9.30am, in front of Cinderella Castle.
Disney has warned fans attending the event that its own cameras will be recording it and are likely to block the view for a large area in front of the castle.
Merida will become the first Pixar creation to join the cast of Disney Princesses. Brave tells the story of the Scottish archer, who rebels against traditional customs and becomes subject to a curse. Boardwalk Empire star Kelly Macdonald voices the character.
