If you watch the ABC Disney show Once Upon A Time, then you already know the Disney princess Mulan is bisexual.
From Huffington Post:
New ground was broken this week when a member of Disney's iconic Princess franchise was queered and it was revealed that Mulan is bisexual.
The hit Disney-ABC series "Once Upon A Time" functions under the premise that classic icons from various fairy tales have been transported to a "real world" town and have lost all memories of their former lives due to a powerful curse.
On this past Sunday's episode, Mulan quietly revealed her unrequited love for "Sleeping Beauty" princess Aurora in a heartbreaking scene that can be viewed above. During the show's previous season, Mulan also developed feelings for Prince Phillip.
