Tuesday marked the first-ever Save the Children benefit gala, and ET was exclusive on the red carpet with the organizations famous allies.
Fresh off maternity leave, Jenna Bush Hager emceed the event, which honored influential supporters such as Jennifer Garner and former Secretary of State Hillary Rodham Clinton.
"I work with the U.S. programs - specifically with early childhood (birth to five) kids in rural America," said Garner who started working with Save the Children five years ago.
"I've always loved kids ... but who I connect with more is moms," said new mom Hager, a former teacher. "You see that all moms want the same things for their kids. They want kids to have healthy, happy, productive lives."
Save the Children works to create change in children's lives by providing food, medical care and education for those in need.
Calvin Klein co-hosted the benefit while providing the wardrobe for many of the attendees.
"I love Calvin Klein Collection," raved New York Giants receiver Victor Cruz. "They always do me right."
