Battle brewing between Hefner's live-in girlfriends?

Melbourne, July 14 : Things are not all happy and joyful at Hugh Hefner's Playboy Mansion, for it seems the battle lines have been drawn between his three live-in girlfriends.

On one side of the ring model Kendra Wilkinson, and in the other are Bridget Marquardt and Holly Madison.

According to reports, Marquardt, 34, and Madison, 28, are extremely jealous of Wilkinson.

"Holly and Bridget hate her," Daily Telegraph quoted a friend of Wilkinson as telling Page Six.

"They're totally jealous. She has her own empire now. She's got a clothing line, a modelling career and an exercise empire. They're just sitting there hangin' with Hef.

"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," the friend explained.

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," the friend stated.

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 said.

"She's definitely been linked with other guys . . . She likes rappers and sports guys," her pal added.
