The pair’s canned 2012 collab has surfaced in full.

Kendrick Lamar and Lady Gaga linked up back in 2012 to create ‘Party Nauseous’, a collaboration originally intended for Lamar’s debut album good Kid, m.A.A.d city.

Creative differences were originally thought to have prevented the track form seeing the light of day. Gaga explained that she was “not willing to compromise musically to the changes [Lamar’s] team was making to my music.”

Recently, though, the singer has been playing the track during transitions on her #artRAVE tour and today the elusive number has leaked online in full. Gaga is on the chorus and delivers a spoken word interlude with Lamar providing the verses.

It’s not the only canned Kendrick and Gaga collaboration: she sung the hook on a version of ‘Bitch Don’t Kill My Vibe’ that didn’t make the album.
