Lady Gaga hopped on Twitter tonight to release the demo version of her boy Kendrick Lamar's standout good kid, m.A.A.d city album cut, "Bitch, Don't Kill My Vibe," complete with artwork and visuals of her in Rio and Colombia. Gaga sings the chorus on the demo version, and the lyrics are slightly different during some parts.
