Lady GaGa is releasing a new track, 'Partynauseous', next month.
The song is a collaboration between the 'Born This Way' hitmaker and rap star Kendrick Lamar.
She tweeted: "I am so excited to announce that a record I've been working on has now become a collaboration with Kendrick Lamar for HIS ALBUM (sic).
"Kendrick Lamar and I are dropping the record September 6. It's called 'Partynauseous'."
Gaga explained her part of the song is based on an incident earlier this year, when she was banned from performing in Jakarta, Indonesia, on her 'Born This Way Ball' tour after hardline extremists in the Muslim country complained her sexy clothes and dance routines would corrupt young people.
She added: "I wrote "PARTYNAUSEOUS" about Jakarta, and my relationship with that country (sic). Wishing I could "get high with the enemy" and make peace (sic). Once @kendricklamar + I started talking about life + his forward thinking views about love + hip hop, the song became something more (sic)."
The track will be released on Kendrick's debut album, 'good kid, m.A.A.d city'. Meanwhile Gaga is also preparing her next album, 'ARTPOP', for release, announcing it recently by posting a picture of the title tattooed on her arm.
