Just as she released her new single “Best Mistake” as a teaser for her upcoming album My Everything, singer Ariana Grande is rumored to be dating rapper Big Sean, who collaborated with her on the single. “Best Mistake” is the second track to be released that Grande and Big Sean worked on together, the first one being her hit single “Problem”.

A source told E! News that Grande and Big Sean had become very close since working together on the songs. “They have been spending more time together and recently have been getting very close. They are both doing great,” said the source, who also claims that Grande and Big Sean’s relationship is official.

Dating rumors were first sparked by a sighting of them watching a movie together in Los Angeles at The Grove. Grande and Big Sean were spotted as they were leaving the theater after a late showing of The Purge, and other accounts claim that they entered the movie house a fourth of the way into the film. The source also reportedly saw them kissing during the movie.

Grande’s love life made the news earlier this month when she announced that she had broken up with 19-year-old Jai Brooks in July. A source said, “When her grandfather was dying, everyone was there for her. People flew to Florida to be with her, but Jai didn’t. Ariana just felt he wasn’t there like he should have been.”

Meanwhile, Big Sean had just come out of his last relationship in the most dramatic way by ending his engagement to Glee star Naya Rivera in February. However, Rivera bounced back a mere three months after the wedding debacle with Big Sean when she married actor Ryan Dorsey in a secret wedding in Mexico.
