Shay Mitchell is pretty in pink as she arrives at Barnes & Noble in Paramus, New Jersey on Friday evening (March 16).

The 24-year-old Pretty Little Liars actress signed copies of her Seventeen Prom cover for a slew of fans and even stayed an hour over to sign for those who didn’t get a wristband!

“So much fun today! Thanks @seventeenmag and Barnes & Nobles in Paramus, NJ!” Shay tweeted.
