Rihanna's landed a major international campaign. While Chanel, Prada and Louis Vuitton are re-living the 90's, Gucci's chosen the twenty-year-old pop star to front their new ad campaign for UNICEF just six months after her lauded performance at Gucci's fall fashion week bash. Rihanna, who's posed for Clinique Happy, Covergirl and H&M's "Fashion Against AIDS" campaign, will star in "Tattoo Heart", a collection of ads for the children's charity in which she'll wear limited edition Gucci for UNICEF pieces. Frida Giannini hand picked her because she, "felt a musician and a beautiful woman was the perfect icon for this campaign." True. And we're all for a good cause. But is it wrong that we worry she'll be contracted to wear Gucci on every red carpet and abandon the up and coming labels she's been so good about supporting? Stylists, take note!
