Big Sean has claimed that Ariana Grande used Justin Bieiber as a weapon, and staged the recent on stage embrace, to hurt him.
According to the sources, Sean, who claims to have been the one to break it off with "immature" singer, feels that Bieber's sudden popping out from backstage, while he was talking to the 'Problem' star, was all planned by her, even though she pushed him away, TMZ.com reported.
The pair started to distance when Sean made his most important appearance of at the House of Blues in West Hollywood, where everyone showed, except Grande, because she had to get ready for the Grammy's the next day.
The rapper, 27, has found it extremely selfish, and claims that he had traveled to see her "10 times more" than her, and that she had once even asked him to shell tens of thousands of dollars to take a private jet to see her.
