Oh God, Ariana Grande and Big Sean are back at it. Following last year’s hit “Right There,” the frequent collaborators/rumored couple show off their chemistry once again on the Key Wane-produced “Best Mistake,” which was released to iTunes on Monday night.

“‘Cause if the water dries up and the moon stops shining, stars fall, and the world goes blind / Boy, you know I’ll be saving my love for you / ‘Cause you’re the best mistake I’ve ever made,” sings Ariana on the tender R&B jam.

Sean responds by calling his girl a “goddess” and showing love to her mom. “When you start as friends, it’s hard to say you’re never going back / If I’m not the one, then I’m the best mistake you ever had.”

Ariana says the song is her favorite off her sophomore album My Everything, which arrives August 25.

In addition to Sean, the album features The Weeknd, Iggy Azalea, A$AP Ferg, and Childish Gambino.
