Cartier chose “Music” as the theme of its third annual Love Day, celebrated yesterday in the U.S. This year's Love Day sees Cartier launch the new Love Charity bracelet with its Love Charity Ambassadors. To tie everything together, the Love Charity Ambassadors are musicians. Ashanti, Common, Emmy Rossum, Eve, Fergie, Good Charlotte, Hilary Duff and Janet Jackson each support different charities in addition to Action Against Hunger, which Cartier supports vigorously.
