At the end of last year, we started to hear rumblings that Future and Young Thug were working on a project.

The two Atlanta artists haven't always been friends. In 2015, they exchanged internet insults highlighted by Thugger calling Future Tito [Jackson] to his Michael.

But they've both made it clear that's all water under the bridge and they would seem like naturals to work on something big together.

Some believe that big thing could be coming as soon as tonight.

Industry website Hits Daily Double has been hearing talk about a "surprise" release that will drop very soon.

BBC's clued-in DJ Semtex is predicting something big tonight, even though we're seeing not anything big among already announced projects.

A lot of fire dropping tomorrow..

Audiomack co-founder Dave Ponte made the "surprise" a collaboration and specific to Atlanta:

A lil birdie told me two of Atlanta's biggest artists are dropping a collaborative project Thursday night

And the ATLiens aren't Outkast.

Does this all sound like Future x Young Thug? We guess we'll know by tomorrow.

Update: It's been confirmed for midnight.

MIDNIGHT #SUPERSLIMEY
