Vanessa Hudgens & Austin Butler Brave the Scares at Knott's Scary Farm Opening!

Vanessa Hudgens and Austin Butler couple up while walking the carpet at the 2016 Knott’s Scary Farm Black Carpet Party on Friday (September 30) in Buena Park, Calif.

The longtime couple made the annual event a family affair by attending with Austin‘s sister Ashley and her husband.

Other stars who stepped out for the fun party were Keke Palmer, Gregg Sulkin, Jennette McCurdy, and Ross Lynch with girlfriend Courtney Eaton and his R5 bandmates.

Guests got to walk through all of the special mazes and ride the roller coasters into the wee hours of the night!

FYI: Austin is wearing Timberland boots.
