Stars Gather for Environmental Working Group's Earth Day Celebration

Hilary Swank, Miranda Kerr, Ashley Tisdale with husband Christopher French, Rumer Willis, and several other entertainment figures gathered at Los Angeles's Skirball Cultural Center on Wednesday, April 22, for the Environmental Working Group x Know Your Values Earth Day Dinner.

The guest list also featured Erin Foster, known for creating and writing Nobody Wants This; Amber Stevens West, recognized from Greek; former Real Housewives of Orange County personality Gretchen Rossi; and Jasmine Tookes, a Victoria's Secret Angel.

Swank took center stage at the 16th annual gathering, receiving the Environmental Working Group Changemakers Award. The honor recognized her efforts in championing California Senate Bill 646, which mandates that prenatal vitamin manufacturers test and disclose the presence of potentially harmful heavy metals in their products. Miranda Kerr participated by leading an intimate discussion at the event, while Foster sat on a panel alongside MSNBC co-host Mika Brzezinski.

In remarks about the recognition, the Academy Award winner expressed her perspective on the achievement: "Receiving the EWG Changemaker Award is a profound honor, but the real victory is the progress we've made together with California Senate Bill 646. As a mother, I believe every parent deserves the peace of mind that comes with knowing the vitamins they take to support their pregnancy have been tested for the presence of heavy metals."

She continued, "Our health is our greatest asset, and I am proud to stand with EWG and HealthyBaby to ensure that no woman is left in the dark about what she is putting into her body. When we demand better standards, we aren't just protecting ourselves, we are protecting the next generation."
