Kendra Wilkinson Sex Tape Partner, Payday Revealed (PHOTOS)

While Kendra Wilkinson's legal battle against porn company Vivid Entertainment wages on, Kendra stands to make millions from the sex tape release she is fighting, Radaronline.com reports.

Her payday includes 50 percent of sales of the sex tape, and her partner in the tape has already pocketed $100,000 for selling it to Vivid, a source told Radar.

That partner is now revealed to be Justin Frye, now 28, a mixed martial arts fighter who started dating Kendra when she was in high school. They broke up soon after Kendra graduated, when she moved into the Playboy mansion. Star has a picture of a shirtless Frye.

Radar reports that Kendra and Frye shot several sex tapes together while they were dating and Kendra left the tapes behind when she moved out.

"Justin had a tripod in his bedroom for the camera and a stripper pole in the apartment," the source said. "Kendra definitely was not shy about being in these tapes. There are tapes of Kendra in really compromising positions ... doing a lot of embarrassing things."

Kendra tried to sell the tapes in 2008 but never struck a deal, and Frye recently cashed in with Vivid, leaving Kendra a cut of the profits.
