Justin Bieber made a guest appearance at an Ariana Grande concert at The Forum in Inglewood, Calif. last night (April 8). According to People, the pair did a touching rendition of “Love Me Harder,” as well as hits such as “Where Are U Now” and “As Long as You Love Me.” And Bieber’s tweet at the show’s end seemed as harmless ever.

But it was during their performance of “Love Me Harder” that Bieber wrapped his arms around Ariana and began “nuzzling” into her neck, according to Mail Online.

It looks as though Ariana’s boyfriend Big Sean wasn’t too impressed with the scene  either. Not long after images of the concert hit the net, the Detroit rapper reportedly took to Twitter, simply saying “Wow.” That tweet has since been deleted but to view a screenshot of it, click here.

What would you do if you were in Big Sean’s shoes? Did the Biebs cross the line?

Check out footage of the duo’s performance below and you decide.

UPDATE: A rep for Big Sean has confirmed to TMZ that a tweet circulating the Internet reading, “This kid is about to learn not to touch my girl like that. Beliebe that” was indeed fake.

“We’re told Justin and Sean are good friends  … and that he and Ariana are just fine,” the rep stated.
