Pretty Little Liars  is about how we look,"  25-year-old actress Lucy Hale tells this month’s Cosmopolitain. "That's terrifying sometimes because you're breaking out, or you feel gross and you still have to be in front of the camera."

"We'll post pictures on Instagram and people will be like, "Y'all are so flawless,'" explains the 50 Shades of Grey star.  "Little do they know it's fake hair, fake eyelashes and a good filter. Little girls see that and think they have to be like that."

Hale used Instagram to unveil her cover portrait on Cosmopolitain as well as her father’s reaction to the cover. "Sorry for the captions dad," she wrote about a photo of herself holding the magazine, which has the headline "Best. Sex. Ever." in large type beside her photo. Two days later, she received a text message from her father on Instagram.

"Saw your pic on Cosmo," he texted. "You look wonderful. Not to(o) crazy about the articles beside your photo. Love u." Cosmopolitan is out on August 12.
