Hugh Hefner's teenage girlfriends are installing stripper poles in their bedroom.

Twins Kristina and Karissa Shannon, 19, do not share sleeping quarters with the 83-year-old Playboy mogul - he stays with his number-one girlfriend, 23-year-old Crystal Harris - but are still thrilled with the space they have at the Playboy Mansion.

Holly Madison, the former girlfriend of Hugh Hefner, is stepping up to discuss her decision to have plastic surgery. The former reality star of "The Girls Next Door" turned star of Las Vegas' Peepshow revue says the decision changed her life and opened numerous doors for her career.

Madison sat down with Life & Style on August 21 before her performance saying, "I always stuffed my bra. In fact, I had a boyfriend for years, and we moved so slowly. We didn't have sex for a long time because I had to gradually bring down my bra size so he wouldn't find out I stuffed my bra!"

Bridget Marquardt is installing a "vintage" trapeze in her hallway. The former "Girls Next Door" beauty - who split from Playboy mogul Hugh Hefner last year - loves using the unusual exercise equipment to stay in shape, and has decided to make it into a feature at her new home.

She explained: "Trapeze is a great workout. It got me in the best shape in my life. The one I'm putting in my house is vintage style - with velvet on the ropes and shiny silver balls on the ends."

Kendra Wilkinson is having a boy. The former Playboy Playmate, who is expecting her first baby with husband Hank Baskett, was thrilled to discover she is having a son during a routine scan.

Writing on her blog, she said: "I just left the doctor's office and I couldn't wait another minute to tell you guys. Hank and I are having a baby boy!!!!!!!!!!!! When the doctor told me I was just like OH MY GOD, I'm going to have a son!!!!! Today is certainly always going to be one of the most memorable days of my life!"

Simon Cowell partied with lingerie-clad models at the infamous Playboy mansion on Saturday night. The TV mogul attended magazine founder Hugh Hefner's annual Midsummer Night's Dream party, held at the 83-year-old's Los Angeles home.

Jon Voight, Shaquille O'Neal, Jack Osbourne, James Van Der Beek, Ryan Seacrest, Randy Jackson, Shannon Elizabeth, Jon Lovitz and Hefner's former girlfriend Bridget Marquardt also attended the bash.
