Holly Madison let a bomb drop last night!  She was caught off guard by paparazzi – well, not a photographer but one with a video and who took sound bites.  You’ll never guess what made her spill the beans…

More pictures after the bomb….

The photographer for TMZ asked for an invite to the infamous Halloween party at the Playboy Mansion.  Whether it was a joke, real or if Holly truly let it slip, this was her reply:

Holly Madison, Hugh Hefner’s number 1 girlfriend could have dumped Hefner because he failed to knock her up??? That makes me laugh.. Why would you want to have kids so badly with someone who’s 83 years old? So they can both be wearing diapers? Oops, that’s cruel, right? Truth may well be cruel at times!

A source reveals exclusively to Scandalist that one of the main reasons Hefner and Madison’s relationship began to deteriorate was their unsuccessful attempts to have children.
