The raunchy homemade video apparently features the ex-Playboy model and her friend Taryn Ryan engaged in a variety of erotic acts.

It is said to have been shot shortly after her first amateur porn film which features her when she was 18 making love to her ex-boyfriend Justin Frye.

That footage was leaked last year and was eventually released as a DVD entitled `Kendra Exposed`.

A source told RadarOnline.com: "They were friends and were hanging out together, with their boyfriends. It`s a long tape, about 45 minutes. And there is nothing left to the imagination.

"Kendra and Taryn started fooling around and then Kendra wanted the light turned off.

"But the camera that was recording them had night vision, so it looks like the Paris Hilton porn tape. Everything is completely clear.

"The girls are laughing at first, and the guys are encouraging them to kiss each other. They started kissing while giggling and then things got hotter."

`Girls Next Door` reality TV star Kendra left the Playboy mansion in 2008 and married NFL player Hank Baskett - with whom she has a son, Hank Baskett IV, with.

When the first X-rated footage of Kendra appeared she tried to stop it from being released but eventually allowed it to be distributed for an up-front fee, rumoured to have been $680,000, and a 50 per cent share of all sales.
