As if we weren't already completely obsessed with Ariana Grande's new song "Break Free, she's got us excited about another new track on her upcoming album, My Everything. We've known about her collaboration with Big Sean for a while, but Ariana just released a short sample of their song "Best Mistake" on Instagram — and it sounds awesome.

From the short bit we've heard, which features Ariana singing a few lines, the track is about a rocky relationship between two people who are meant to be together. It has a super-chill and romantic vibe. We can't wait!

Big Sean helped make Ariana and Iggy Izalea's track, "Problem," so we're sure this song is going to be amazing too.
