Hugh Hefner is trying for a baby with girlfriend Holly Madison.

The 28-year-old blonde and 81-year-old Playboy founder are so desperate for a baby they are spending nearly all their time having sex.

Hugh Hefner's favorite girlfriend Holly Madison is planning to get pregnant.

The blonde beauty sparked rumors she was pregnant when she didn't drink on a recent holiday in Monaco. Fellow live-in girlfriend Bridget Marquardt has revealed, while Holly is hoping to have a baby with Hugh, she is yet to conceive.
