Grins lit up 7 World Trade Center on Friday night, as Billy Bush and Naomi Campbell hosted Operation Smile's 25th anniversary dinner. Guests including Lydia Hearst, Fabiola Beracasa, Dr. Lisa Airan, and executive chairs Vanessa and Donald Trump, Jr., took in an exhibit by Nigel Parry and Melanie Dunea from The Journey of Smiles, a photography book charting the duo's travels with the nonprofit. The evening also included a J. Mendel runway show. "What I love about Operation Smile is that what you give goes right to the kids," said designer Gilles Mendel of the organization that has performed over 100,000 surgeries on children with facial deformities. Naomi Campbell added, "These new smiles reflect the brilliance inside each child and give them the hope and confidence they need to reach their goals."
