Holly and Bridget Hate Kendra

"Holly and Bridget hate her," a friend of Wilkinson told Page Six. "They're totally jealous. She has her own empire now. She's got a clothing line, a modeling career and an exercise empire. They're just sitting there hangin' with Hef."

The friend expounds, "Kendra was never really Hef's girlfriend. She was cast for the show [E!'s 'The Girls Next Door'] because Bridget and Holly are old, and they needed a young hot girl for Hef. She was selected from a bunch of Playmate wannabes." Madison is 28, Marquardt, 34. Wilkinson celebrated her 21st birthday last year.




Wilkinson is said to be eyeing her exit from "The Girls Next Door" and the famed mansion next season. "She's definitely out," her friend said. "There are too many rules and Holly and Bridget want her gone. They're so mean to her."

Wilkinson has had a hard time sticking to the rules of the Playboy mansion - which include a curfew and a strict "no dating other men" line.

"She goes out all the time really late and parties," her pal says. "She's definitely been linked with other guys . . . She likes rappers and sports guys."

Holly is Hef's number one girl, the only one who lives full time in his bedroom and allegedly rules the roost with an iron fist.

But Bridget and Kendra Wilkinson are his two other blonde stunners who have become the darlings of the Hollywood paparazzi.

Gorgeous Kendra was spotted celebrating her birthday while the others were conducting a massive search for the 55th Anniversary Playmate.

And when Paul turned up to the search, he started asking the questions others wouldn’t - “Who's really number one? How does someone earn that distinction? Don't you really hate Kendra?"

The answers given by Holly and Bridget were as sexually open and uninhibited as the former ECW owner's penchant for controversy.

"We like to do things together," Bridget tells our man Paul.

She adds: "There used to be a bunch of girls at the Mansion and things were not so happy... now that we're down to the three of us, NOW we know how to get along!"

Wait 'til you hear Holly's discussion with Paul about why "three" is the magic number, and how it always leaves the door open for more friends to join the girls with Hef!
