Uh-oh.
Post Malone was caught on camera messing around with World's Most Haunted Object. In the above video shared by TMZ, American rapper Post Malone can been seen with host Zak Bagans playing around with a “haunted box” named the "Dybbuk box" inside Bagans’ Haunted Museum in Las Vegas.
It's supposedly haunted by an evil spirt and also went on to inspire the 2012 movie, The Possession. Eeeek.
