A lavish birthday party with a Marie Antoinette theme is thrown for Holly.

It’s Christmas at the Mansion and the staff work like elves to create a winter wonderland for Hef and the Girls - complete with a snow covered front lawn!

After helping to decorate a Star Wars-themed float for the world-famous Tournament of Roses Parade the girls decide to get to work on their New Year's resolutions.

It's Holly's big chance to serve as apprentice editor under the tutelage of Playboy's west coast editor, Marilyn Grabowski.

Holly, Bridget and Kendra make plans for a photo calendar.

The ladies take a trip to Vail, Colo., to snowboard and relax at a luxury resort.

It's a romantic Valentine's Day at the mansion for Hef and his three girlfriends.

The eagerness to learn who will become the next Playmate of the Year has the Mansion buzzing as the girls get to know the finalists.

While both Bridget and Kendra spend the weekend with their families, Hef and Holly share some time at home.

Breaking with tradition, Hef and The Girls Next Door celebrate Hef's 81st birthday with a huge party weekend in Las Vegas.

When Bridget sends her dog to obedience school, Kendra decides to enroll herself in charm school. Holly, meanwhile, continues with her photo editor apprenticeship for Playboy.

Kendra preps to participate in the celebrity portion of the Toyota Grand Prix. Meanwhile, Bridget gets her Porsche customized and Holly goes green and buys a Toyota Prius.

Hef and the girlfriends receive an invite to attend a local Renaissance Faire. Bridget -- a Ren Fest enthusiast -- organizes period costumes and an Elizabethan language coach for the gang. Dressed as the "visiting king of France," Hef delights the rowdy crowd and charms the "Queen of England," even after Kendra puts her language coaching to use and calls the queen a "sausage wallet." Bridget notes that she loves being a wench for a day, but knows that she and the girls are all queens at the Mansion.

The Playmate of the Year Luncheon is always one of the biggest events of the year at the Mansion. But this year, it’s even bigger.
