Released on November 9, 2018, “Who R U?” is the second single from Oxnard. The track features backing vocals from legendary producer Dr. Dre, who also co-produced and mixed the track.

The song artwork seems to continue the movie theme that is prominent on the artwork for the track “Tints.” On the artwork for this song, Anderson is wearing a suit, and is looking in a mirror that is reminiscent of one seen in a dressing room. This could signify that he is feeling like a movie star, and he wants to look the part.
