Kendra Wilkinson in Kendra on Top Teaser: 'I Flushed My Wedding Rings'

Hell hath no fury like a Playmate scorned!

In this exclusive teaser obtained by PEOPLE, Kendra Wilkinson demonstrates that she'll hold nothing back for the third season of WE TV's Kendra on Top.

As images of the tabloids flash in the background, Wilkinson, 29, describes what it was like to learn that Hank Bassett – her 31-year-old husband of five years and father to their two young kids – cheated on her earlier this year with a transsexual model.

"Every word that came from the tabloids," Wilkinson says as her eyes fill with tears, "Boom … boom ... boom. When did he do this? While you were eight months pregnant."

Wilkinson goes on to to describe how the news felt like she was "getting shot," and that it prompted her to take a very dramatic step: She flushed her wedding rings down the toilet.

A source told PEOPLE that the reality star is already meeting with divorce lawyers and ready to start a new chapter in her life, even though the couple continue to appear together for the sake of the show. Earlier this month, Wilkinson and her soon-to-be-ex staged a barbecue at their Calabasas home.

The new season of Kendra on Top returns Oct. 3 on We TV.
