Her former friend and Girls Next Door co-star made some shocking claims about both her and their former shared boyfriend Hugh Hefner in her new book, but now, Kendra Wilkinson is speaking out against Holly Madison's claims.

Did Hank Baskett Want Kendra Wilkinson To Cut All Ties With 'Playboy?'

In an interview with People, Wilkinson, 30, says that Madison, now 35, had always had an agenda and behaved with an inflated ego that she was more important than she actually was during her time at the Playboy Mansion.

"My perception was that she acted like a First Lady," Wilkinson said. "You know, she had to play a part, play a role every day being there. Like, 'I have to be this in order to get this.'"

Holly Madison Slams Kendra Wilkinson As 'Fake'

Wilkinson went on to say that Madison's claims now are simply born from a motivation to get revenge after she didn't get exactly what she wanted in the end.

"How could [Holly] want kids and [to] get married to him and then, next thing you know, say these types of things about Hef? It's just out of revenge, and I feel bad for Hef. But you know what? He's an amazing human being," she said.

"Holly, you can tell, had this ulterior motive every minute being at the Mansion, and that motive was--it was clear as day--she wanted Hef's kids, she wanted a piece of Playboy and she wanted to marry Hef for, obviously, his will," she added. "That didn't happen. So what do you think's going to happen? Revenge. So we're witnessing some revenge here."

However, Madison has still had some harsh words for Wilkinson, not only ripping apart her own attitude at the mansion, but also claiming that Wilkinson's now husband, Hank Baskett, whom she met at the mansion, originally had eyes for fellow Playmate Kayla Collins--which caused a meltdown by Wilkinson at the time.

"I assumed Kendra felt threatened by another petite, energetic platinum blonde running in front of the cameras," Madison said in her book. "Later, I would hear through the grapevine that Kendra's future husband, Hank, was apparently after Kayla before he met Kendra. I have no idea if this is true or not, but it would explain the freak-out."
