Meanwhile, Jenner, 26, arrived with her girlfriends in a black corset and matching lace veil, not a mask.

Or him, for that matter.

Eyes wide shut the party was just an opportunity to pretend. 1999 erotic thriller starring the then couple Tom Cruise as well as Nicole Kidmandepicting a man infiltrating a secret society s*x party.
