Mariah has responded to Diddy's challenge in regard to her fragrance. From contactmusic.com:

"I heard about this competition, and I wish Puff (Combs) all the best with his new fragrance. ... I think we're actually appealing to different types of women. M by Mariah Carey is about being unforgettable, not unforgivable. ... It's not about a menage a trois or a one night stand, it's for the woman who wants the man to fall in love with her immediately, stay in love, and treat her like royalty."

The article also details how Diddy has invited her, Jennifer Lopez, Gwen Stefani and Sarah Jessica Parker to do a blind smell test in front of the Sean John store in NYC. He says that the loser would have to pay for a shopping spree.
