The song, a remix of "Ain't It Funny", features additional vocals from Ja Rule (Jeffery Atkins), Caddillac Tah, and Ashanti.
The song was written by Lopez, Atkins, Tah, Cory Rooney, Irving Lorenzo, and Ashanti.
Over a reworking of the beat to Craig Mack's "Flava in Ya Ear" (produced by Easy Mo Bee), Lopez sings about "dropping a boyfriend who keeps messing up".
The song was due to be recorded the following day, but was postponed due to the September 11 attacks.
In the United Kingdom, the remix peaked at number four, becoming Lopez' seventh top-ten hit there.
