Romeo Must Die

I am extremely curious about this one song in the movie Romeo Must Die. The song was playing when Han ( Jet Li ) was with Trish ( Aaliyah ) at her apartment. Maurice and his gang just arrived at her place and the song was playing in their Escalade. The song is not included in the movie soundtrack. It's a hip hop song and when I heard it, it goes something like " at the parking lot, we at it again " Can someone please tell me what the song's name and artist is?
