Do toy story characters appear in disney princess movies?

The only verified information we have is that Toy Story is a franchise created by Disney and Pixar, and the characters listed belong to that series. No source provided indicates that any of these characters cross over into Disney Princess films. Disney Princess movies are produced under the Disney brand but separate from Pixar’s Toy Story universe. Because the evidence does not mention any crossover appearances, we cannot state that Toy Story characters appear in Disney Princess movies.
