The rumors have been swirling for the past few weeks that Scarlett Johansson, the face of Dolce & Gabbana's new makeup line, would also be fronting the design house's new scent, Rose The One ($48 to $90). Today, People confirms with a first look at the new ad. On the other front, the ad for Mariah Carey's new fragrance, Mariah Carey Forever, has also just been released. Both endorsements feature the stars dressed in slinky, form-fitting gowns while striking seductive poses. Each ad also works in a monotone element, with warm, café au lait shades in Mariah's and soft, rosy tones in Scarlett's. If you had to choose your favorite of the duo, which one wins out?
