Ariana Grande & Elizabeth Gillies Used to Kiss on 'Victorious' Set - Here's Why!

Ariana Grande and Elizabeth Gillies used to lock lips while filming Victorious!

The “God is a woman” singer and the Dynasty actress had a pretty amazing reason for kissing each other on set.

In part two of the behind-the-scenes footage of Ariana’s “Thank U, Next” music video — which Elizabeth stars in — the duo prepares to shoot the “Jingle Bell Rock” dance from Mean Girls.

Ariana and Elizabeth stand back-to-back, and Liz jokes that she’s attempting to transfer some glitter from their outfits onto her body.

“Remember when we ran out of lip gloss and kissed on Nickelodeon?” Elizabeth asks, to which Ariana replies, “I know! Guys, want to know a little-known fact?”

“When no one would hear us and we would be begging like, ‘We need a touch-up please,’ and they would be like ‘rolling,’ we would look at whoever was glossier at the moment, and to add more color, we would be like [makes kissing gesture], ‘Let’s go,’ and we would transfer the color,” Elizabeth reveals. “That happened.”

“That was really funny, I had forgot about that,” Ariana adds.
