New Yorkers for Children Gala

"It was so emotional and bittersweet," said Liv Tyler (here with husband Royston Langdon) of a moving speech by a program graduate. "I couldn't stop crying."

"There are 17,000 foster children in New York City, and they need all the support they can get," said Naomi Watts, here with Liev Schreiber.

LeAnn Rimes treated the crowd to a five-song set, including a powerful rendition of the Gershwin classic "Summertime."

Diane Kruger looked like a goddess at Cipriani, which served its famous Bellinis from silver trays.

LeAnn Rimes, Naomi Watts and Isabella Rossellini all looked radiant.

"This is something we can solve," said host Diane Sawyer, who mingled and posed for photographs with the event's honorees.

Designer Zac Posen made his way down the red carpet looking dapper in a blue velvet blazer.
