SEAN 'DIDDY' COMBS is so intent on celebrities looking good at 28 August's (05) MTV Video Music Awards, he's offering $100,000 (GBP55,000) to the best-dressed stars.

The rap mogul, who will be taking on hosting duties at the Miami show, wants stars competing on the red carpet for the cash in the contest he's dreamed up.

He says, "I want to have a 'style-off' called the Diddy Fashion Challenge. I'm bringing cash that night and will give it to the best-dressed male and female for their favourite charities."

Combs is also hoping for a "moment" at the show - much like Madonna and Britney Spears' 2003 liplock. He adds, "The Madonna-Britney kiss, that was a moment. I'm encouraging moments - whether it's controversial, whether it's the outfit you have on, whether it's a speech that's heartfelt."
