Ariana Grande reunited with her Victorious costar Elizabeth Gillies, and the longtime friends locked lips in a moment that left both 22-year-olds squealing with laughter.
"It has to be pretty though," Gillies says in a video posted to Grande's Instagram on Monday, counting down to the kiss.
In June, the Sex&Drugs&Rock&Roll actress spoke to PEOPLE about being close with Grande ever since they got their big breaks in the 2008 musical 13.
"She's like blood to me, she's like my sister. So unless we have a massive falling out, nothing will be happening there," she said, laughing. "We lived together, I've known her since what feels like the beginning of time."
