The long-rumored Lady Gaga and Kendrick Lamar collaboration has finally arrived!

"PARTYNAUSEOUS" was written by Gaga and Kendrick back in 2012 and was scheduled to be included in the rapper's debut album, but was later scrapped due to creative differences between the artists' teams.

"I apologize to the fans that this situation is confusing," Gaga said. "When I collaborate with an artist I work solely with them, not with their camps or management. It's purely organic and creative. I love Kendrick dearly as a friend, but was not willing to compromise musically to the changes his team was making to my music. He's a good kid, its just sometimes a mad city."
