She might be famous for her gorgeous brows, but Brooke Shields is now making her lashes the focus as the spokesperson for lash-lengthener Latisse. And at last night launch event for the product in L.A., stars including Angie Harmon, Debra Messing, Mandy Moore and Jewel turned out to help Brooke celebrate the newest innovation in beauty. The FDA-approved, prescription-only treatment promises to grow lashes longer, thicker and darker with continued at-home use. And Brooke was more than happy to be among the first celebs to try it out. “I was quite shocked with how quickly I can see results!” she told PEOPLE.com of the eight weeks and counting that she’s been using the product. “I was skeptical. It’s amazing.” Brooke wasn’t the only convert on hand. Mandy Moore told PEOPLE.com, “I can’t put fake lashes on by myself, so it’s nice to know that there’s something out there that can benefit you in that process.” But the evening also marked the launch of “Latisse Wishes,” a public awareness and education campaign supporting the Make-A-Wish Foundation.
