Kanye West has promised to start following in the footsteps of smelly rock stars.

The American rapper has vowed to wear just one memorable outfit for the MTV Video Music Awards and its after party next month.

"Whenever you see rock stars they just wear the same thing and it's all sweaty and then you see them the next day and they stink. That's the whole thing about being a rock star - you could wear the same outfit all week," Kanye told US Weekly magazine.

"So I'm going to pick one extremely good outfit and just wear it the whole time. The party is going to be too crazy, I won't have time to change."

West has been nominated in five different categories, including Male Artist of the Year, and Video of the Year for his Stronger music video. The ceremony takes place on September 9.
