Inside UNICEF Snowflake Ball: How Katy Perry Stole the Show

It was certainly a #GivingTuesday at the UNICEF Snowflake Ball on Tuesday evening at Cipriani Wall Street in New York City, where stars turned out in droves to support the charity's "belief in zero" efforts to end the preventable deaths of children.
UNICEF Ambassadors Angie Harmon, Danny Glover, Téa Leoni, and former ambassador Katie Couric were all in attendance, as well as Katy Perry, Christina Ricci, Bryant Gumbel, Audrey Hepburn's son Luca Dotti, Jenna Bush Hager and Henry Hager, Mark Consuelos, Kyle MacLachlan, Tyson Chandler, and more.

Perry, who was named UNICEF's newest Goodwill Ambassador at the event, stunned in a burgundy, velvet Naeem Khan gown on the red carpet, but changed into a glittering gold Michael Kors number to perform her hit single "Unconditionally," which she said was inspired by a UNICEF trip she took to Madagascar.

"I believe young people have the power to change their own lives, with our help," the 29-year-old songstress said of her new role. "I am honored to join UNICEF as a Goodwill Ambassador, and committed to doing everything I can to help children and adolescents who come from such different backgrounds but want the same thing: a brighter future."
