Lil Uzi Vert has said he is considering retiring from the music industry.

But before he does, he will drop Barter 16.

It looks like Uzi -- who is non-binary and uses they/them pronouns -- has a surprise collaborator for the project:  Birdman.

Baby was in the studio with Vert and London On Da Track during recording.

“THUGGIN @liluzivert @londonondatrack STUNNAMAN RICHGANG @cashmoneyofficial,” the Cash Money boss captioned.

What does having Birdman in his life mean for Uzi?
