Photos of Rihanna Lighting the Snowflake For UNICEF and Gucci

Rihanna, Madonna, and Blake Support Kids and Gucci

Rihanna was on hand to light UNICEF's Snowflake in NYC last night before hitting the red carpet in a more dramatic gown alongside Blake Lively and Madonna. The snowflake marks the beginning of holiday shopping season, which we've already gotten a great start on around here with all our fabulous gift guides. Rihanna was also there to officially launch her Tattoo Heart Collection for Gucci, which also benefits UNICEF. The dresses were varied, but Madonna certainly stood out in her unique green LV number, she is the face of the brand after all, on a break from her world tour tonight in Philadelphia. She has a few nights off after that, and according to court records, she will be officially divorced as of tomorrow. As for Rihanna, we'll get to see her strutting her hot stuff on stage this Sunday at the American Music Awards.
