Lots of fabulously dressed celebs came together last night to celebrate an addition to their jewelry collection -- Cartier's newest collection of Cartier LoveCharity bracelets. Rihanna, Eva Mendes, Usher, Faith Hill, Tim McGraw, Julianne Moore, and Rachel Weisz are among the new Cartier LoveCharity bracelet ambassadors, which means a portion of the proceeds from their corresponding colored bracelet goes to a charity of their choice.
