Ariana Grande played the Forum in Inglewood last night as part of her Honeymoon Tour.
She brought out Justin Bieber to sing the song 'As Long As You Love Me.' During the performance, Bieber was getting pretty handsy with Grande. This delighted the crowd, but it seemed to bother Grande at times. And it infuriated the 21-year olds boyfriend Big Sean. (Who is actually on the original song with Bieber.)
Sean quickly delated the tweet, so we're not sure if Bieber saw it when he sent out this Tweet, which could be seen as mocking Sean.
It's interesting that Sean wanted to go after Bieber but then backed off. Maybe the little fellow has more industry juice than we imagine. Or maybe Sean is afraid the tyke's been training with Mayweather.
Video of the show is below. Biebs gets grabby at about the 13 minute mark.
Update: Big Sean says the threatening Tweet is a fake.
