Ariana Grande and Big Sean may have cited scheduling conflicts as the reason for their split last week, however, only days after the duo called it quits after eight months of dating, sources close to both Grande and Big Sean are offering up information regarding what led to their breakup.

TMZ reports that Grande initially became upset with her rapper beau when he dropped his track "Stay Down," in which he allegedly talks about the "Problem" singer's "billion dollar p***y."

Big Sean raps, "I ain't even gonna lie, I got a million dollar chick / With a billion dollar p***y / Everytime I c*m, I swear to God I feel like I be rich."

A source close to Grande reveals that she was put-off by the lyrics, adding that when her grandmother confronted her inquiring about the meaning behind Big Sean's rap, Grande was especially embarrassed.

However, Big Sean has admitted in the past that Grande has listened to his entire album with him before it was released, although it's unclear whether or not she expressed her concerns at that time.

In addition, another source adds that Grande was the one who paid for the most of the expenses in regards to their relationship, despite sources close to Big Sean revealing that it was he who dropped thousands of dollars to visit her while she was on tour.

Sources close to Grande reveal that the "Break Free" songstress footed the bill for vacations and private flights so they could see each other frequently.

However, Big Sean called out his ex for her "selfish" behavior after she skipped his House of Blues performance in February due to her Grammy performance being the next day.

However, sources close to Grande admit that it was the songstress who believed her boyfriend was selfish, seeing as he didn't take into consideration the prep required for her performance the next day.

Grande's voice was "strained" by rehearsal for the awards show and was given strict instructions by her vocal coach to remain silent for the remainder of the day, something that upset Big Sean, the sources confirmed.

As for rumors that suggest the onstage Justin Bieber "hug" was a calculated plan by Grande to make Big Sean jealous, sources confirm that the "Bang Bang" singer never asked the pop star to hug her or engage in the stunt and that Big Sean never expressed any concern over the move after it was brought up in the media.
