Young Buck has fuelled the war of words between himself and former rap boss 50 Cent by slamming the G-Unit mastermind in the words of a new song.

News of the new tune, My Interview, comes just days after 50 revealed he axed the rapper, real name David Darnell Brown, after he spoke out about dissent in the G-Unit camp.

Young Buck sparked the rap row after telling Yo! Raps Magazine he had yet to be paid any royalties owed to him since signing with 50’s G-Unit Records.

And now he’s hurled the latest blow by sending a new song to MTV.

He raps, "I hear the same things that you heard/That 50 kicked him out or Buck sniffs coke and he flips out/It’s too late, the whole world know what I be about/S**t, I do make mistakes like any other man/S**t, I recoup off an album, quicker than you can."

Despite the friction between the two rappers, 50 Cent has revealed that Young Buck will appear on G-Unit’s upcoming Terminate On Sight album, which is slated for release on 24 June (08) - even though he is no longer a member of the group.
