Kendrick Lamar and Lady Gaga have revealed that they are officially working on a track together. After the blonde pop star recently attended his show at the Pitchfork Music Festival in Chicago, the two were seen tweeting back and forth like old friends.

The relationship seemed to be strictly personal at first but has now spilled into the professional realm as Lady Gaga announced the name of their collaborative track, "Partynauseous," which she posted to Twitter. She explains that the song is "about Jakarta, and my relationship with that country. Wishing I could 'get high with the enemy' and make peace."

In a tweet that has since been deleted, Lady Gaga wrote that the track would drop on Sept. 6. This would be well-before Lamar's first official album, good kid m.A.A.d city, due Oct. 2. Mother Monster isn't the only person that the "Swimming Pools (Drank)" rapper teamed up with this album -- he worked with Dr. Dre on "The Recipe," for which a video has been shot and is set for release in the coming months.
