In a move that is likely to set headbangers frothing at the mouth with rage, one-time Guns N' Roses guitarist Slash has defended his decision to use Black Eyed Peas' vocalist Fergie to sing on a new version of his former paymasters' global smash 'Paradise City.'

The pop singer joins Cypress Hill -- famed purveyors of beats and blunts -- on the new rendition which appears as a b-side of the Japanese edition of Slash's new single, 'Sahara.'

Standing his ground, the cork-screw haired plankspanker was moved to write on his Twitter account saying, "Until now, not too many people have heard Fergie sing rock & roll but she sings it better than most dudes I know. She's a screamer at heart.

Quite whether the track is set to appear or not on the guitarist's forthcoming album, 'Slash and Friends,' remains to be seen Scheduled for a release in early 2010, the record will feature guest appearances from Red Hot Chili Peppers' Flea, Alice Cooper and the ever-busy Dave Grohl.
