The rapper and R&B singer posted what looks like an album cover together under the name Twenty88. "4/1" is the caption, which pegs Friday as the likely release date.
Twenty88 also have a few short snippets of music and visuals teased on Twitter. As in the joint photo, Aiko is seen rocking an orange wig.
Aiko and Sean are longtime collaborators, on hits like "I Know" and "Beware." Big Sean dropped the track "Get My Shit Together" over the weekend.
