While she reportedly profited from it, Kendra Wilkinson still isn't pleased that a sex tape she made when she was 18 is now available for sale.

"It's extremely embarrassing," the Kendra star told E! News in her first interview since Kendra Exposed was released by Vivid Entertainment on May 28.

"I am a very open person. I am very honest about my life. But a sex tape was definitely not what I wanted in my life."

The sex tape stars Wilkinson and ex-boyfriend Justin Frye, who allegedly sold the footage to Vivid.

"It just had to come out now," she told E! News while choking up. "It had to come out when I finally cleaned up my life. It wasn't for anybody else's eyes to see except for ours."

While Wilkinson reportedly formed a company to shop the tape -- and several others -- in 2008, she didn't follow through with the plan, opening the door for Frye to reach his own agreement.

Still, Wilkinson 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.

Wilkinson's interview with E! News anchor Ryan Seacrest will air Tuesday at 7PM ET/PT on E!.
