FIRST LOOK: Rihanna's ad for Gucci 'Tattoo Heart' charity collection

We've known for a while now Rihanna is the new ambassador for Gucci's UNICEF Tattoo Heart ad campaign, and now we've had our first (edited) glimpse of the full-length film (to be released on 9 December on gucci.com). Ri-Ri swings around on a hoop suspended in the air, with one of the gorgeous white leather Gucci bags slung across her shoulder. Have a look for yourself and make sure you check out the behind-the-scenes vid too...
