Emma Watson might have won us over with her spot-on portrayal of Belle in this year's live-action retelling of Beauty and the Beast, but she'll always be Hermione Granger somewhere in our hearts. And the British beauty proved that the Harry Potter franchise, which she took on in 2001 as a child actress, still holds a very special place for her when she had a run-in with a former co-star Wednesday evening.

Watson, who was at the Tribeca Film Festival to promote her new sci-fi thriller The Circle, was a vision in white as she posed for the cameras in an elegant off-the-shoulder number featuring a thigh-high slit. While making the red carpet rounds, the 27-year-old gave us a major Hogwarts flashback as she met up with fellow Harry Potter star Bonnie Wright, who played Ginny Weasley in the film series.

Did Watson send out another blast of premiere invitations to the Harry Potter group chat? Either way, the fact that Hermione and Ginny are still friends IRL is truly a magical thing.

For the after-party, Watson slipped out of her white gown and into a black jumpsuit with an off-the-shoulder neckline that mirrored her earlier red carpet look. Now that's a très chic post-premiere outfit change!
