Last week it was announced that Dr. Dre would appear in the upcoming GTA Online expansion The Contract, which drops later this week. In the trailer, Dr. Dre performed a new song with Anderson .Paak, and there'll be other new tracks in the expansion.

Last night (12 December) Dr. Dre shared an image of him in a studio with an orchestra, and wrote, "I just finished recording an album with Marsha Ambrosius. Casablanco I had a blast!! This is some of my best work!!"

As HotNewHipHop notes, Dr. Dre and Ambrosius previously worked together on some tracks from his last album - 2015's Compton - including "Darkside/Gone", "Satisfiction", "All in a Day's Work" and "Genocide".

It's currently unclear if Dr. Dre's music contributions to the upcoming GTA Online expansion will be tied to his new album.

The Contract will be available on GTA Online from 15 December.
