Holly Madison's book signing was allegedly attended by her former housemate turned enemy Kendra Wilkinson. According to a report from People, a preview for "Kendra On Top" teased that the ex-Playmates will have a face off.

The said reality show of Kendra Wilkinson showed her extremely upset about accusations made by Holly Madison in her book "Down the Rabbit Hole." The memoir exposed the alleged manipulative behavior of magazine founder Hugh Hefner, who also supposedly consented drug use and bullying inside the infamous Playboy mansion.

"What Holly is saying is extremely false," Kendra Wilkinson said in the preview.

"I'm like, 'Where did this s--- come from?' She's living as a fake cartoon, I think. She's not living on Earth with us."

"That's how it felt, all those years living there. She really played this role. This fantasy type of role. It wasn't because of Hef. Hef never told her and forced her to do that. Maybe that's why she didn't marry her," she narrated.

According to a report from Reality TV World, Kendra Wilkinson's series preview showed her planning to confront Holly Madison during one of her book signings.

The 30-year-old revealed what she wants to say when she walks up to her former "Girls Next Door" co-star with a copy of her tell-all book. "Sign this, b****," Kendra Wilkinson said.

"Someone needs to have a voice against this. Hef won't do it. He's too nice of a guy."

"It's just weird how someone can get away with such a thing," she added.

The end of the "Kendra On Top" teaser showed Kendra Wilkinson about to enter Holly Madison's book signing.

"I'm not going to let this bitch get away with something like that," she said.

"Things might get pretty ugly. We left the mansion a long time ago. I would be respectful if she were to tell her own story like I did. But don't bring others down."
