Officially marking the spooky season, X Factor star Olly headed down to the theme park in Surrey to try out the new horror maze, Studio 13.
Draped in a tattered grey fabric, 30-year-old Olly dressed up as a blood-stained zombie as he joined the themed characters to pose for pictures.
Going all out to be as scary as possible, Olly sported dark, ghoulish eye make-up with fake red blood around his mouth - very realistic!
'Troubkemaker' singer Olly tweeted: "Crazy night out with these scary creatures @THORPEPARK Fright Night! It's a must! Cabin in the woods was insane."
Along with Studio 13, the park has also opened up new mazes for its most popular rides including SAW the maze, Cabin in the Woods, My Bloody Valentine and The Blair Witch Project.
Joining Olly for the night was the likes of X Factor stars Alexandra Burke and Diana Vickers Made In Chelsea's Binky Felstead and TOWIE's Jasmin Walia.
Fright Nights is now open to public from 3pm until10pm.
