Ariana Grande has moved on from donut-licking to stealing kisses from co-stars: Specifically Liz Gillies, with whom Grande starred in Victorious.

Grande uploaded a video of the smooch, which was followed by a lot of screaming, to Instagram, cheekily captioning the post: “my favorite video of all time @lizgillz (p.s. this was totally posted by accident).”

Gillies, who currently stars on FX’s Sex&Drugs&Rock&Roll, has shared the stage with Grande before. Below, they perform “Give It Up” on Victorious.
