Justin Bieber Gets Fresh With Ariana Grande Onstage & Big Sean Reacts

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, Sean wrote "“This kid is about to learn not to touch my girl like that. Beliebe that.”

And ….

The Big Sean/Justin Bieber feud is over before it even started ... or more accurately ... it never existed in the first place.
A rep for Big Sean tells TMZ the tweet going around in which Sean threatened Bieber for laying hands on Ariana Grande during a concert ... is a fake.
Justin and Sean are good friends ... and that he and Ariana are just fine.
Another tweet of Sean's -- "so many times in my life I wish I could of been at 2 places at once" -- also sounded like it was about Bieber ... but TMZ was told it had nothing to do with JB, and Sean just misses friends and family while on the road.
