The Pretty Little Liars star has signed on to front a series of ads for the beauty brand, as well as its m.powerment campaign, which was set up to raise awareness about dating abuse.
She tells People.com, "I'm incredibly proud to partner with a brand that is as passionate about empowering women as I am. I've been a fan of mark's products for years, but it was important to me to work with a brand that is truly about beauty on the inside and the outside."
And makeup bosses are glad to have Hale on board - company president Meg Lerner says, "Lucy embodies our mission of empowerment and what it means to make your mark on the world. We're thrilled she's joining us in time to celebrate our 10th birthday."
In addition to Greene, U.S. reality star-turned-fashion designer Lauren Conrad has also served as a spokeswoman for the firm.
