Jason Derulo is known for his irresistible hotness [1], but the "Talk Dirty" singer was truly frightening when he performed a melody of his hits dressed up as Game of Thrones' Night King [2] at Maxim's Halloween [3] party in LA on Saturday.

Read on to see more photos of Jason as the Night King . . . if you dare.
