The world has been watching the two singers closely after it first came out that Ariana Grande and Big Sean had called it quits, and as time goes by it seems like their breakup wasn't anywhere near amicable - and it seems he even wrote a heavy dissing song about his former flame.

Before it came out that Ariana Grande and Big Sean had broken up, rumors flied about that they were both preparing a collaboration with rap legend Eminem, but if the rumors of their bad split are true, it seems like there's no future alliance in the works after they ended things very badly.

It seems like there are several versions out there as to why Ariana Grande and Big Sean split; Christian Post reports the mildest of them all, as they supposedly broke things off over commitment and money issues - this report claims that things went downhill for the couple after Sean's House of Blue appearance last February, when his girlfriend failed to attend.

It seems like, aside from that, the only way Ariana Grande and Big Sean would see each other was when he traveled to see her, while she was too selfish to do the same for him - even though she had a Grammy performance scheduled for the following day.

Youth Health Magazine reports that, when Ariana Grande and Big Sean were still together, Sean made sure that his girlfriend always listened to his new tracks - though maybe the "Love Me Harder" singer missed at least one lyric, as "Stay Down" references his ex's "billion-dollar p***y," which sounds heavily offensive whoever it might be about.

In the meantime, following the breakup, it has been reported that Grande might be going out with superstar Justin Bieber, according to Celebrity Dirty Laundry; for months on end, there have been rumors of a love triangle between Ariana, Justin and his ex Selena Gomez.

However, as it has been widely said that the Canadian star is currently dating "Keeping Up with the Kardashians" sister Kendall Jenner, the plot thickens even further.

There's still no confirmation as to why Ariana Grande and Big Sean ended their 8-month relationship.
