Singer Ariana Grande and rapper Big Sean shocked the world this week when they announced that they were splitting up after only eight months of dating. While the duo cited schedule conflicts as the reason behind their breakup, new sources claim that Justin Bieber may be slightly responsible for the split.

Did Justin Bieber Breakup Big Sean & Ariana Grande?

On Thursday, TMZ reported that an insider close to the rapper says that he and his ex were having trouble before, but after Bieber and Grande's raunchy performance, he knew it was the final straw.

Apparently Grande didn't make enough time for her man after he traveled more than 10 times to see her perform.

TMZ quotes the insider saying, "But the crowning blow was just after the breakup. They were still talking and the door was slightly open for a reconciliation, when Bieber jumped onstage in L.A. and grabbed Ariana from behind."

Bieber landed himself in some hot water with the rapper after the singer got a little too touchy with Grande during their performance in Los Angeles earlier this month.

The singer joined the stage at Grande's concert at the Forum in L.A. and the two performed As Long As You Love Me and they got a little touchy.

Despite the fact that Grande did try to push Bieber off of her, the Detroit rapper believes that the whole thing was staged to hurt him. The break up came about a week after the incident occured but neither Big Sean or Grande have confirmed that the story is true.
