[UPDATE] January 15, 2020 2:01pm EST - Highsnobiety has been told through an official source that the source of the this rumor, the whiteboard seen below, is not an official tracklist.

Eagle-eyed fans have spotted a clue in a recent Instagram post that could indicate that Drake and Kendrick Lamar will appear on Big Sean's new mixtape.

It all started with YK Osiris, who shared an Instagram gallery after visiting Big Sean. In the background of one of the posts was a whiteboard, which has caused speculation regarding the project's guest artist line-up. Apparently Young Thug, Future, and Lizzo may have also made the cut.

The list is titled Detroit II and is presumably the follow-up to 2012's Detroit, which Kendrick also featured on alongside J. Cole, French Montana, and Juicy J, to name but a few. What's more, in his 2019 track "Overtime," Big Sean dropped the line, "I know your favorite one, dawg, I'm 'bout to drop the sequel."

Find YK Osiris' IG gallery below and keep scrolling for the whiteboard close-ups.

In case you missed it, Kendrick is also apparently gearing up to drop a new album soon. Find out everything we know about that here.
