Lil' Kim, who has had a long-running public feud with Minaj, has now recorded the track 'Black Friday' - a take on Minaj's debut album title Pink Friday.
Discussing the track with radio station Hot 97, she said: "[Minaj] just really jumped out the window. You've got to be careful when you pick fights."
Lyrics to the song include: "It'll be a murder scene/ I'll turn a Pink Friday into Friday 13/ I hate you 'Lil Kim clone clown/ All this buffoonery/ This s**t stops now".
Lil' Kim previously claimed that Minaj had "disrespected" her, insisting: "I love when people copy me, that's a compliment. But when you bust shots at me and throw pebbles at me, as if I don't even exist and you don't see me standing here, I'ma bite you!"
Minaj's is on course to debut at number two on the US album chart.
