Ariana Grande Cheated on Jai Brooks with Big Sean? 'Problem' Singer Dating Naya Rivera's Ex Boyfriend

Ariana Grande, 21, and Big Sean, 26, seems to be taking their friendship to a new level as speculations are doing the rounds that the two are dating.

Grande and Big Sean became close friends since the two were working together in the hit song, "Problem" and were recently spotted going on a movie date in Los Angeles. It is also reported that they got intimate during the screening of "The Purge".

"They have been friends since they made the song together. They have been spending more time together and recently have been getting very close. They are both doing great," the source told E! Online.

However, Grande and Big Sean have not made any official announcement on their alleged relationship. 

Grande has just come out of a relationship with Jai Brooks and it has been speculated that she got close to Sean when she was still in a relationship with Brooks, according to a report by Celebdirty Laundry.

The "Problem" singer reportedly broke up with Brooks, as he didn't find time for her when her grandfather passed away.

"When her grandfather was dying, everyone was there for her. People flew to Florida to be with her, but Jai didn't," said the source to the Website. "Ariana just felt he wasn't there like he should have been."

Grande even took to Twitter to express her feelings and how she learnt who loves her during the times of crisis.

"You learn a lot about love, life and the people around you during a time of crisis," Grande began the long post. "July was painful for many reasons but of all the personal loss I suffered last month, the loss of my grandfather, a true gentleman, was the only one that truly mattered," the "Bang Bang."

Grande has also dated "The Wanted" singer Nathan Sykes but they parted ways after a few months.

Whereas, Sean was previously engaged to "Glee" star Naya Rivera. The two called off their wedding for unknown reasons. However, it was a difficult decision for the rapper as per the official statement by his representative who claimed that Sean wants best for Rivera and all the rumours related to their break-up were untrue.

Rivera married Ryan Dorsey in a secret ceremony in Mexico just three months after breaking up with Sean.
