Ariana Grande And Liz Gillies Kiss And Accidentally Post The Vid

Can't stop giggling.

Ariana Grande reunited with her "Victorious" castmate Liz Gillies on Monday night, and things got a little silly. So silly, in fact, that their shenanigans were accidentally posted on Instagram.

In the cutest, funniest Instagram video, Ari and Liz decide to channel their inner Katy Perry and see what it's like to kiss. So they did. And now it's on the internet. And now it's trending.

"my favorite video of all time @lizgillz. (p.s. this was totally posted by accident ????)" Ariana wrote on Instagram.

Accident. Right.

I'm pretty sure her fans won't be able to forget this. Donutgate? What's donutgate?
