Oops! Look like Christmas came a little bit early for Ariana Grande and Big Sean fans anxiously waiting to hear the couple's upcoming collaboration "Research" -- the track has just leaked online!

The track -- which is set to appear on Big Sean's upcoming album, Dark Sky Paradise (out Feb. 24) -- features Big Sean on the rhymes and Ari on the hook, infusing the rap-heavy song with a little bit of R&B sass.

"Do you remember, do you remember / Do you remember when you had nothing to hide?" she croons on the chorus, reminiscent of Ashanti back on those early 2000s R&B tracks that we played incessantly. In fact, the whole tune has a total throwback vibe, giving us all the nostalgic feels about the best parts of late '90s/early '00s R&B and rap back in the day.

We love that Big Sean enlisted his leading lady to sing the hook on the song, because it automatically makes the track that much better. It's legitimate proof that Big Sean and Ariana Grande are a kickass couple, both personally and professionally. Plus, you know a song is good when Big Sean can drop a line about a hair in the sink (ew!) and we still love it.

Check out Big Sean's "Research" featuring Ariana Grande in the video above. (Note that the audio is pitched -- as in, their voices are slightly higher -- and it's NSFW for language.) Happy listening!
