Diddy Poses Perfume Challenge to Gwen, Britney and J. Lo

Now that the war between Kanye West and 50 Cent has been settled, Sean "Diddy" Combs is proposing a challenge of his own -- over perfume.

Diddy is so confident about Unforgivable Woman, his first female fragrance, that he's asking Jennifer Lopez, Britney Spears, Sarah Jessica Parker and Gwen Stefani to put their respective scents up against his. "My fragrance smells better than theirs," he told PopEater. "Women know how they want to smell, but as a man, I know how a woman should smell. I bring another element into it."

Diddy -- who name-checks Demi Moore, Megan Fox and old flame Lopez as some of Hollywood's best-smelling ladies -- is no newcomer to the fragrance game. Unforgiven, the male cologne he introduced last year, became the top-selling fragrance of 2006. And like its male counterpart, the ad campaign for the Unforgivable Woman is mired in controversy, thanks to a racy, three-minute "moviemercial" that censors deemed too hot for TV.

"We're selling sensuality, passion and provocativeness," Diddy said. "[The advertisement] shows some of the naughty things people do. It's very erotic, but it's also authentic. We've also been getting a little flack for it because people haven't seen a black man portrayed like this in a prime-time fragrance ad. It's revolutionary and a little bit shocking to people.

"It's not really racy to me," he continued. "I mean, I only get half naked."
