You know Ariana Grande and Liz Gillies from Victorious, but they showed off a whole new side of their friendship when the "One Last Time" singer "accidentally" uploaded a video showing them giving each other a smooch. It was a very quick peck, and they were laughing the whole time, so it seems like they were just being playful.

Once the pop star realized that she accidentally uploaded the video to Instagram, she says she found the whole thing hilarious.

And even though the video wasn't supposed to go public, it's actually "great."

Since the vid was never meant for our eyes, we're kind of surprised that she didn't delete it. But it seems like she has nothing to hide.

Are you surprised Ariana posted this video? How did you react when you saw it? Let us know in the comments!
