Despite Mariah Carey's diva demands, the songstress knows how to give back. Mimi and hubby Nick Cannon attend the 2009 UNICEF Snowflake Ball last night in NYC. The UNICEF Snowflake is a special symbol for the world's most vulnerable children.These iconic snowflakes — at 57th Street and Fifth Avenue in New York and on Rodeo Drive in Beverly Hills — hang as a reminder of UNICEF’s commitment to reach a day when zero children die from preventable causes.
