Big Sean was not happy when Justin Bieber joined his girlfriend, Ariana Grande, on stage on Wednesday night (8th April). Bieber got a little bit too close to Grande whilst the two were performing at Grande's concert at the Forum in Los Angeles.

Bieber joined Grande on stage for three songs during her concert and although the two were dancing flirtatiously, Bieber got a little handsy as they performed 'As Long As You Love Me'. Towards the end of the song, Bieber called Grande over and, standing behind her, started to wrap his arms around her. Grande looks distinctly uncomfortable with Bieber's move and quickly removes herself from his embrace. The two continue performing as usual but footage of the incident soon went viral.

Big Sean reportedly lashed out at Bieber after seeing the footage. According to TMZ, he reportedly tweeted but later deleted: "This kid is about to learn not to touch my girl like that. Beliebe that."

Apparently, Bieber did not realise he had caused any offence as he later tweeted thanking Grande for allowing him to share the stage. "Love the stage. Thanks for having me Ariana Grande and thanks LA. Gotta tour again soon," Bieber wrote. 

21-year-old Grande and Big Sean confirmed they were dating in October last year after rumours about the nature of their relationship had circulated for months. Big Sean shouldn't be too worried though as Bieber is taking a break from dating. 

"Well, at this point in my life I'm so focused on myself that I'm not looking for a girlfriend. I'm just trying to make sure I'm 100 percent so I can add to the person I want to be with," Bieber told USA Today at the end of March.
