Hef with (left to right) Kendra Wilkinson, Holly Madison and Bridget Marquardt

After a wild ride with his party posse, Hef is still throwing the biggest parties in L.A. with his favorite threesome. Holly Madison, Bridget Marquardt and Kendra Wilkinson, better known as the Girls Next Door, have become synonymous with the Playboy name while their fan base continues to grow.

Hef met his number one gal Holly while she was working as a Hawaiian Tropic model. In August 2001, after a year of coming to Mansion parties, Holly received a date with Hef and soon after, a spot in his bed at the Mansion. Bridget, who dreamed of becoming a Playmate for years, earned a couple test shots for the magazine, but never made it to Playmate. Instead she became a regular at the Mansion and received her own room a year later. Kendra joined the girls shortly after when Hef spotted her photo on the Mansion's fax machine. She was one of the body-painted models for Hef's 78th birthday bash and within a month, she was a girlfriend.

In 2005, the threesome took to the TV reality scene on E! with their show The Girls Next Door, which followed the daily lives of Hef and his leading ladies. The show instantly became a huge success and fans couldn't get enough of Holly, Bridget and Kendra. The third season of The Girls Next Door was the second-highest season premiere in E!'s history.

The girls have graced the cover of Playboy magazine three times -- November 2005, September 2006 and March 2008. They've made cameo appearances in Scary Movie 4, General Hospital and Nickelback's video "Rockstar," to name a few. They have also become quite the world travelers with Hef vacationing to places such as St. Tropez, Paris and Monte Carlo. With this crazy threesome the fun never stops and Mr. Playboy is enjoying every minute of it.
