Ariana Grande kissed a girl and she liked it.

The 22-year-old shared a video on Instagram of herself kissing her best friend Liz Gillies, 22, on the lips – and according to the singer, it was an ~accident~ (not the kiss of course, but the public share).

The video, which is still on her Instagram account, was originally supposed to be sent to Liz directly, but while editing it on IG, the pop star claims she accidentally pressed publish.

Ariana decided not to delete it because it's her "favorite video of all time" – and we have to agree, it's pretty great. Her reaction directly after the kiss is just too funny!
