“Pretty Little Liars’” star, Shay Mitchell, signed copies of her cover photo on Seventeen magazine’s August issue at Barnes & Noble on Union Square. The store was packed with fans of all ages accompanied by friends and families. We were very excited to capture this experience on camera to share with the millions of seemingly upset Twitter followers that were unable to make it. Shay was joined by Seventeen’s Editor-in-Chief, Ann Shocket, who signed copies of Seventeen’s new beauty book. Aside from acting in “Pretty Little Liars,” Shay Mitchell hosts Seventeen’s program “Beauty Smarties Showdown,” in which participants go head-to-head in wild hair and makeup challenges from the magazine. Shay’s first acting role was as a model on Degrassi. She also portrayed her role in real life when she modeled for American Eagle Outfitters.
