Big Sean is reportedly planning to diss his ex-girlfriend Ariana Grande in a new song. According to the rumor mill, two major events have pushed the rapper into deciding to end things with the "Love Me Harder" singer as well as planning to come up with a diss track to spite her.

"Big Sean cannot wait to put his relationship with Ariana on blast in a song," a source revealed to Hollywood Life.

According to the report, the first incident that disappointed Sean was when a lot of his friends, family, and fans went to the House of Blues in West Hollywood to show their support for him at a very important show. Everyone was there - except for his then girlfriend.

It was indeed a huge and important show since it was jam-packed with a lot of today's biggest and richest artists, namely, Justin Bieber, Kanye West, Chris Brown, Kendall and Kylie Jenner, Tyga, A$AP Rocky, Jay Z, and Jennifer Lopez. TMZ reported that Grande was not able to attend her boyfriend's big gig since she was too busy getting "ready" for the Grammys, which was scheduled the very next day.

The aforementioned guests also had to attend the Grammys, but they were able to watch him perform his segment. According to the report, Sean thought that Grande's excuse was immensely selfish. "He traveled 10 times more than she did to see her," a source who claims to be close to the rapper said.

The second incident that allegedly spurred Sean's decision to break up with the former Nickelodeon child star was when Justin Bieber hugged her from behind while they were performing onstage in Los Angeles.

Although it was clear that Grande was not comfortable with the set-up and immediately pushed Bieber away, Sean's insecurities reportedly convinced him that the arrangement was his then-girlfriend's idea.

"Sean claims it was him who broke off the relationship because she was immature," the source added. "He claimed once she demanded that he blow tens of thousands of dollars to take a private jet to see her. Sean, who grew up poor, felt she was a spendthrift - a sign of immaturity."

Following the highly publicized split, Grande finally spoke up for the first time. "I love you babes so much," the songstress wrote on her Twitter page, talking with her fans and followers. "You are a bunch of angels, honestly. You love/care is appreciated so much. I am good, I promise.
