With a June wedding
on the horizon, Hugh Hefner
and fiancée Crystal Harris
huddled close all night at the Playboy
Golf Lingerie and Pajama Party at the Playboy Mansion in L.A. The two "looked smitten," according to a source at the soiree, where the soon-to-be 85-year-old also received a life-sized birthday card from Playboy
Golf CEO Ajay Pathak and a bevy of Playmates.
