N-Dubber and former flame of Tulisa, Fazer has premiered his debut solo single Killer.
Killer is due for release 26 August and is taken from Fazer's new album, which is out later this year.
A creepy teaser video that goes with the track sees the rapper in a cell with a straitjacket on, played on loop.
Fazer is the last member of N-Dubz to release a solo single. Dappy released No Regrets last September and Tulisa got to Number One with Young back in May.
So what do you think of Killer?
