After racking up millions of views on YouTube and releasing several mixtapes, Big Sean is finally ready to drop his first studio album. The G.O.O.D. Music rapper rounds up Chris Brown for “My Last,” the No I.D.-produced lead single off his Def Jam debut Finally Famous: The Album, dropping in March.

The track, which previously leaked without Chris’ vocals, sees the duo taking turns rapping and singing over the bouncy piano-laced beat. “Where that alcohol? You ain’t even gotta ask/ ‘Cause I’ma drink it all, like it’s my last/ She a seven in the face but a 10 in the ass/ She even look better by the end of my glass,” rhymes Sean before throwing it to Breezy for the chorus. “I’ma hit this drink up like it’s my last/ I’ma hit this night up like it’s my last,” he sings.

Listen to the celebratory tune below.
