Those are not really books but I think you may be interested to know what the most famous celebrity sex tapes are and I will try to list them here.
By far the best known and most watched celebrity sex tape is Kim Kardashian & Ray J sex tape. You can click the link above to watch it in full from the official site for $4.95 (believe me is worth every penny).
Kim Kardashian sex tape is not the only one celebrity sex tape. I have about 15 others on my list and will add them here as soon as I get time to watch them.
