The Return of Hef

E! is taking viewers back inside the Playboy Mansion when the second season of "Girls Next Door" premieres this Sunday at 9PM ET.

Hugh Hefner and his girlfriends -- Holly Madison, Bridget Marquardt and Kendra Wilkinson -- let cameras in on every aspect of their lives. The hour-long premiere episode focuses on the planning of Hef's 80th birthday bash.

Besides organizing the party, each of the girls is stressing out over what to get the man who gets everything. Not to give too much away, but Bridget decides to jump out of a cake and strip for Hef. So she prepares for the dance by practicing the seductive dance in front of a few friends and family -- including her dad!!!
