The 43-year-old rapper has reportedly been working on a new album for some time now, and while he has yet to reveal the release date for the record, its first single "Stressin" is proof he's in no rush to do so.
"So let me ask one question, do it look like we stressin'? / Cause we ain't," Lopez sings at one point in the track.
Fat Joe and Lopez, 45, have previously collaborated on tracks like "Feelin' So Good" in 1999 and "Hold You Down" in 2005.
