Justin Bieber Joins Ariana Grande Once Again On Her Honeymoon Tour: Watch

Pop Perspective: Rihanna's "BBHMM"
All four Idolator editors review Rihanna's new single "Bitch Better Have My Money."

It’s no surprise that Justin Bieber and Ariana Grande are good friends and like to perform together — they are both managed by Scooter Braun, after all. But during Grande’s Inglewood, CA stop of her Honeymoon Tour last night (April 8), it looked like the two were a little more than friends!

Bieber, who is now reformed from his bad boy image, joined the mini diva on stage where he helped sing “Love Me Harder” and his Jack U collaboration, “Where Are You Now.” Once the two began to sing Believe’s “As Long As You Love Me” (which features Ari’s boyfriend, Big Sean) that’s when Bieber got too comfortable. He proceeded to grab the popstress’ waist, and she quickly backed away from him. Let’s hope Sean Don is cool with all of this!

Watch the video below (the waist grabbing occurs at the 13:07 mark), and let us know if you think the two artists were just trolling the crowd.
