In an interview last year, Kendrick Lamar revealed that he had spent time in the studio with Prince. In a new feature from the Grammys, Lamar revealed the exact nature of those sessions. He wanted Prince to sing the hook on his To Pimp a Butterfly track "Complexion (A Zulu Love)."

After Rapsody revealed the news, Lamar confirmed:

That's true. Prince heard the record, loved the record and the concept of the record got us to talking. We got to a point where we were just talking in the studio and the more time that passed we realized we weren't recording anything. We just ran out of time, it's as simple as that.

Last year, Prince brought out Lamar to perform "What's My Name."
