Lil' Kim provided background information about the track:
I do remember being pregnant at the end of that album, where I couldn’t really finish some of the songs and that’s how Lil’ Cease ended up on ‘Crush on You.’ He wasn’t supposed to be on that record, but I was sick and I had to go away and clear my head because I was pregnant. I wanted to finish the album because that’s what I wanted. I really wanted to display my talent to the world.
“Crush On You” samples the 1979 song “Rain Dance” by The Jeff Lorber Fusion:
