The longtime friends and pot pals plan to release the new duet later this summer.
Confirming the news in an interview with Beats 1 host Ebro Darden, rapper Snoop insists the new track is a rallying call to bring people together following the Black Lives Matter protests.
"The reason why we gonna make this record is because black and white matters right now, the love that we have for each other (sic)," Snoop said. "It's not about colour; it's about love - it's about the appreciation of humanity. I love you as a person, Willie, I love your music... When you build that brotherhood, the colour is out the window."
