"Problem" singer Ariana Grande has just recently released another single for upcoming album, "My Everything." Is collaborator Big Sean the lover behind new song "Best Mistake?" Are the two hip-hop stars really dating?

"Best Mistake" is the latest release from Ariana Grande's sophomore album "My Everything," and marks the fourth song we've heard from the record after summer hit "Problem" featuring Iggy Azalea, "Bang Bang" with Jessie J and Nicki Minaj, and the dance club banger "Break Free" produced by Zedd.

In her hot new song "Best Mistake," Ariana Grande slows things down. The "Baby I" singer returns to her R&B roots, with a sensual and emotional jam. With minimized production and instrumentation, Grande's voice finally shines through once again. According to Us Magazine, Grande called the track her "favorite one yet."

Listen to the new song, "Best Mistake," here!

The 21-year-old soulful songstress croons, "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."

And who did she choose to collaborate with on the new track?

Why of course she chose rumored boyfriend and frequent collaborator Big Sean!

Midway through the song, 26-year-old Big Sean, who is rumored to be dating Ariana Grande, raps, "I know sometimes it's hard to realize I'm the man that you need / I had a dream we branched out started a family tree / And I feel like that everything we do is overdue / You asked why I love your mom so much cause she's an older you."

The two have recently struck up a romance, after developing a relationship due to their collaborations of "Right There" and "Problem." According to E! News, Ariana Grande and Big Sean "are dating."

A source told E! News about the boyfriend and girlfriend, explaining "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."

While the musicians and their reps have yet to comment on the matter, it seems pretty obvious now that they've released another romantic song together amidst the rumors!

Both Grande and Sean have recently split from serious relationships, but seem ready to move on in the dating world.

Forget Grande's ex Jai Brooks and Sean's ex Naya Rivera, it's great that the talented and attractive musicians are moving on! Who's hoping the Ariana Grande and Big Sean dating rumors are confirmed soon?
