Lucy Hale & Chris Zylka - Just Jared Halloween Party 2012

Lucy Hale and her on-and-off-again boyfriend Chris Zylka are all smiles at the 2012 Just Jared Halloween Party held at Siren Studios Orange on Saturday (October 27) in Los Angeles.

The 23-year-old Pretty Little Liars actress dressed as a rainbow unicorn while the 27-year-old Amazing Spider-Man actor went as late rocker Kurt Cobain.

Chris didn’t stay too long at the party. “I have an important photo shoot tomorrow but I can’t say what it’s for,” he told JustJared.com. “I’m really excited though!”

Lucy was seen hanging out with her roommate and pal Cassie Scerbo. She hit up the Creative Recreation hay maze and the mesmerizing 3-D glow in the dark tent. “Thank you @JaredEng for the grandest Halloween party I’ve ever attended,” Lucy tweeted.
