Hank Baskett's alleged mistress, Ava Sabrina recently wrote a letter to his wife, Kendra Wilkinson urging her to leave Baskett.

In the letter, obtained by the National Enquirer, Sabrina insists that she had an affair with Baskett and reminds Wilkinson that she also took a polygraph test to prove the affair actually happened.

Sabrina then continues the letter by describing Baskett as a "lying, troubled person, and I believe, 'Once a cheater, always a cheater.'" She also encourages Wilkinson to "divorce Hank and save yourself from any future heartache and pain," and offers to meet up with Wilkinson to clear up any doubts regarding Baskett's alleged affair.

Baskett's alleged affair with transsexual model, Ava Sabrina was first reported back in June.

Sabrina opened up about the affair to the National Enquirer and claimed that Baskett payed her $500 to meet up and engage in sexual acts not involving sexual intercourse.

"Hank never identified himself by his real name. But he used, I believe it was Steve, as his name," she explained. "Hank absolutely knew that I was a transsexual and he told me that I was the only transsexual he's ever been with," London alleged. "He thought I was beautiful."

Though Sabrina insists that she had an affair with Baskett, he continues to deny the affair rumors, the Hollywood Life reports.

Wilkinson and Baskett's relationship drama continues to unfold on the new season of their WE TV reality show, "Kendra on Top."

Despite, Sabrina's allegations and polygraph tests, Wilkinson has gone on record to say that she will continue fighting for her marriage.

During an interview with Access Hollywood earlier this month, the former Playboy model said that she would give Baskett "the benefit of the doubt" in regards to his cheating.

"At the end of the day, he comes from an amazing place, he's a perfect guy, he's never done me wrong, he's never treated me wrong, if he was, I wouldn't be with him now," she added.
