An unedited master copy of Kim Kardashian's sex tape almost burned up in a raging fire at Vivid Entertainment on Saturday night. The tape was secured in a safe inside Vivid co-chairman Steven Hirsch's office when the blaze erupted; he was miles away at an L.A. Clippers game, TMZ.com reported.

Hirsch got the 911 call and left immediately, as the safe contains not only Kardashian's tape but every unedited master of every celebrity sex tape in Vivid's ossession, including the ones starring Kendra Wilkinson, Pamela Anderson and Tommy Lee, Jimi Hendrix, Vince Neil, Tom Sizemore, and Chyna and several other tapes that have never seen the light of day.

Hirsch's safe was singed but the contents were intact.
