Demi Lovato & Ariana Grande hike to Manson murder house

Demi Lovato and Ariana Grande had a ghoulish girls' night out on Friday (19Feb16) when they visited the Charles Manson murder house.

The two horror fans took a midnight hike to the former Los Feliz, Los Angeles home of Leno and Rosemary LaBianca, who were killed by Manson and members of his infamous The Family cult in the late 1960s, and then hit Twitter.com on Saturday (20Feb16) to recount the experience.

Ariana wrote, "Friday night was lit and by lit I mean terrifying because we hiked on foot to the Manson murder house... and by lit we mean everyone s**t themselves."

"@ArianaGrande and by s**t ourselves we mean we literally s**t our pants... Except yours had glitter in it," Demi added. "And the Chanel logo."
