The former Playboy model's explicit video - which shows her having sex aged 18 with her boyfriend Justin Frye - has become a hit before it has even been released, with pre-order figures completely overshadowing the raunchy film sold by the model-and-party girl.
Both videos have been released through pornographic video company Vivid Entertainment.
Justin was paid $100,000 for the footage, while Kendra is to receive up to 50 per cent of the profits made from sales of the tape.
The blonde beauty initially tried to block the release of the recording when news of it first emerged, but after realising the earning potential of the DVD, which will be titled 'Kendra Exposed', she decided to enter negotiations with Vivid Entertainment.
The 24-year-old star - who is married to American footballer Hank Basket and has a five-month-old son Hank Baskett IV with him - started dating Justin in high school, but split from him shortly before she embarked on a relationship with Hugh Hefner and moved into the Playboy Mansion.
