Are Ariana Grande and Big Sean dating? Pair releases new single "Best Mistake" last Monday.

Rumors of Ariana Grande and Big Sean dating started even before their newest collaboration "Best Mistake" hit the stores last Monday. The new song definitely intensifies the buzz.

Ariana's new single "Best Mistake" is taken out of her latest album, "My Everything," with Big Sean collaborating in the vocals and production. The rapper joins her halfway through the song, a ballad of a tumultuous romance.

While the single is usual fare in R&B, the rumored romance between the pair adds a new dimension of excitement to fans and listeners. Ariana even went so far as to say that "Best Mistake" is her favorite song to date. Other releases from her "My Everything" album are also collaborations with different artists.

She teamed up with Iggy Azalea in "Problem," which topped the charts of the summer; "Break Free" is an upcoming single with Zedd, and will hit stores late August.

So, are Ariana Grande and Big Sean dating? Everything's rumor up to this point, with the two recovering from relationship fallouts of their own. Ariana is also moving on from the death of his grandfather.

Ariana is quoted on love and loss in separate statements: "You learn a lot about love, life and the people around you during a time of crisis." On the aftermath of her grandfather's death in July: "I thank everybody who was here for me when I needed them as the ones who weren't really broke my heart."

Big Sean just came out from a messy breakup with "Glee's" Naya Rivera in April; the couple was already engaged. His rep comments: "After careful thought and much consideration, Sean has made the difficult decision to call the wedding off. Sean wishes Naya nothing but the best and it is still his hope that they can continue to work through their issues privately."

News of Ariana Grande and Big Sean dating won't come as a surprise. Both have yet to comment on the rumor (usmagazine.com).
