If you have ever watched the reality TV show The Girls Next Door then you know that 81-year-old Hugh Hefner lives in his Playboy Mansion with three girlfriends. To me, his ladies seem a bit like caricatures; Kendra Wilkinson is the hot tomboy, Bridget Marquardt is the sweet one, and Holly Madison, the relatively smart one. Maybe that's just me.

Madison is also the one who shares Hef's bed each night (at least on the show) and she has made no secret of her desire to become a mother and have a more normal life with Hefner. She claims he is the best lover she ever had and was recently quoted as saying "I want to have kids with Hef in the next year or so and when that happens I just want it to be me and him."

It seems that she just may get her wish. Rumors were swirling at the Monte Carlo Television Festival that Madison is pregnant with Hefner's 5th child. She missed Kendra's birthday bash, has been steering clear of alcohol and is engaging in a lot of baby talk.

An insider says, "While the other girls hit parties wearing next to nothing and looking all glamorous, Holly stayed covered up and in the background. She even wore a jacket for many of her interviews."

A jacket? Well, if that doesn't say pregnant, I don't know what does. And that hat. Her choice of head-wear has got to be the result of crazy hormones, right?
