Mandy Moore for Garnier and Other Celebrity Beauty Campaigns of 2017

The Big Little Lies star is the newest YSL Beauty Global Makeup Ambassador. Her first project with the brand will be "Before the Light," where she will serve as makeup guru to up-and-coming musical artists. She will also work on the Tatouage Couture lipstick campaign, which launches August 2017.

"YSL Beauty has always been one of my favorite brands. Their ability to combine the chicest of styles with a raw edge has always been to me one of the best ways to express yourself through fashion and beauty. Nothing is forced, nothing is fake, but everything is bold, strong, and unafraid. I'm very excited to work with this legendary and timeless company," Zoë said in a press release.
