Last night, Ariana Grande took her "Honeymoon Tour" to L.A., and brought out Justin Bieber to do "Love Me Harder" and "As Long As You Love Me." Over the course of his two-song appearance, the young pop star couldn't keep his hands off Grande, who you'll remember is currently dating Big Sean.

In a since-deleted tweet (view it in the gallery above), Sean wrote "“This kid is about to learn not to touch my girl like that. Beliebe that.”
