Kendra Wilkinson apparently didn't limit her sex tape co-stars to men only.

Explicit home-video footage featuring the Kendra star and a female co-star named Taryn has surfaced, Kavi Cermak -- who previously dated Taryn -- told RadarOnline in a Friday report.

Cermak's claim has been confirmed by multiple sources familiar with Wilkinson's "x-rated past," according to RadarOnline.

In addition, sources told RadarOnline that sexual toys are used in the footage -- which also includes the former The Girls Next Door star having intimate relations with multiple partners.

"This is really, really graphic and showing her in compromising positions; things you would think would be embarrassing for her," a source told RadarOnline.

Earlier this month, Vivid Entertainment announced its plans to release Kendra Exposed -- a sex tape Wilkinson made several years ago  -- on May 28.

Justin Frye -- Wilkinson's ex-boyfriend who sold Kendra Exposed to Vivid and stars alongside her in it -- is involved with the video that recently emerged, according to RadarOnline, which added Vivid is also in possession of the new footage.

Similar to the footage with Frye, Wilkinson made the tape with Taryn before she moved into the Playboy Mansion as one of Hugh Hefner's girlfriends in 2005, according to RadarOnline.

Wilkinson recently reportedly reached a financial agreement with Vivid in which she will receive up to 50% of the sales generated by the release of Kendra Exposed.
