I can't find the song that matches these lyrics

The lyrics that are part of the bridge go (female) cause I'm having your baby and it's driving me crazy. then a male voice sings ok Ima stand up/step up and be a real man. It sounds like avant and someone else but I don't think it is him. It is an r & b duet that came out around the late 90's or early 00's.

that's 'one night stand' by latocha scott and j-shin
