THERE doesn't seem to be any rivalry between the world's two most famous white rappers -- rising star Bubba Sparxxx has said he is grateful that Eminem has had such massive success.

The rapper, who has worked with Timbaland and Missy Elliott, told NME that Eminem's success helped him become respected as before him white rappers weren't thought of as cool.

"Eminem restored my credibility," he said.

"Before him the last white MC was Vanilla Ice and Vanilla Ice was a debacle. It was an uphill battle for us white rappers after that.

"Eminem gave credibility back to the institution of white people being involved in hip-hop."
