The New Princesses of Equestria

The day after Pinkie and Rarity became alicorns, Applejack and her siblings were harvesting apples to make cider for Twilight's birthday. When they got to the last tree, there was one apple that did not come loose. Applejack climbed up and pulled with all of her might. Eventually, the apple broke free. However, she pulled so hard that the remaining force caused her to fall out of the tree. She managed to catch herself and then she saw that the apple was really her gem of Honesty. She admitted that she did not know that her gem had turned into an apple. Knowing that they were making apple cider, they decided to get up early. This way, they could make as much as possible for both Twilight's party and to sell.

The next day, they started making cider, and then Applejack began to glow orange all of a sudden. When the light cleared, she looked different. She had a horn on her forehead, and wings had sprouted from her back. Applebloom commented how pretty her sister looked, only for Applejack to hear a voice in her head.

"Your name is Applejack. You are Equestria's new Princess of Honesty."
