Ariana Grande and Big Sean dating rumors is going around the news lately. According to an E! News source, the two artists who worked on Grande's hit together have taken their friendship to a new level.

"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 tells E!

An onlooker tells E! News the two are spotted at The Grove in Los Angeles after leaving the theater from a late showing of The Purge. The witness said that the pair came in about a quarter way into the movie, and only about three people recognized them. Source also claims that he saw the pair kissing during the film, and left before it was over.

US Weekly noted that the pair collaborated for "Best Mistake," Grande's latest single in her upcoming album My Everything. The R&B song says, "Cause you're the best mistake I've ever made / But we hold on, hold on / There's no pot of gold at the rainbow, sweet Jesus / But we're holding on, hold on."

Reportedly, Grande has been romantically linked to Big Sean after breaking up with her boyfriend Jai Brooks for the second time earlier this month. On Aug. 4, the singer posted a vague message about her love troubles, writing, "You learn a lot about love, life and the people around you during a time of crisis." Explaining that the loss of her grandfather was a painful experience in July, she added, "I thank everybody who was here for me when I needed them as the ones who weren't really broke my heart."

People flew to Florida to be with her, but Jai didn't," the E! News source said. "Ariana just felt he wasn't there like he should have been."

Meanwhile, the rapper was engaged to Glee star Naya Rivera but the pair ended up splitting in April after Big Sean, "made the difficult decision to call the wedding off." Following the public breakup, Rivera "shocked everyone" by marrying actor Ryan Dorsey three months later in a Mexico.

Reportedly, Big Sean's representative remained mum on the matter and Grande's rep has not responded yet.
