Big Sean’s Reason For Ariana Grande Breakup — Justin Bieber Stage PDA

Yes, you read that right! Big Sean thinks it was Ariana’s idea to be all touchy with JB on stage, an insider shared with TMZ!

During Justin’s surprise appearance at Ariana’s LA concert, he called her over to stand in front of him at one point. He then seductively wrapped his arms around her waist but she did NOT seem too happy about it! You can watch the whole thing for yourselves HERE!

You could see her pushing his hands away from her body the entire performance, but Big Sean still thinks the whole thing was “calculated” by Ariana, the insider shared.

If Big Sean thinks it was Ariana’s idea to show off PDA on stage with JB, we can understand the reason for the breakup, however, it did NOT look like Ariana had those intentions at all.

Big Sean Thought Ariana Was Selfish?

Another thing that really ticked Big Sean off was when Ariana didn’t show up to his huge House Of Blues concert on Feb. 7. EVERYBODY showed up to support him, except for Ariana!

When we say everybody showed up, we mean it! Kanye West, 37, Justin Bieber, 21, Jennifer Lopez, 45, Chris Brown, 25, Jay Z, 45, A$AP Rocky, 26, Tyga, 25, Kylie Jenner, 17, andKendall Jenner, 19, were all there!
