"I haven't seen him since I left the mansion," Fox News quoted Madison as saying. She added: "And it is my first time filming "Girls Next Door" as a single lady so that's exciting."
Madison was joined at the bash by the other 'Girls Next Door' beauties and Hefner's ex-girlfriends Kendra Wilkinson and Bridget Marquardt. The trio helped the Playboy Mogul's three new leading ladies 'Crystal Harris, Karissa Shannon and Kristina Shannon' in the preparations for Hefner's birthday.
And seeing all his current and ex-loves joining him for the party, the octogenarian tycoon was overwhelmed with happiness. He said: "As you can tell I am very, very happy. To celebrate my birthday with new girlfriends and former girlfriends is perfect, its wonderful. I've had a life well-lived with so much satisfaction, I enjoy just looking back."
