Playboy's Hefner to wed again at 84

Playboy magazine founder Hugh Hefner, 84, has revealed that he has become engaged again

Hefner said in a Twitter message early yesterday that he gave a ring to girlfriend and Playmate Crystal Harris, saying she burst into tears.

"This is the happiest Christmas weekend in memory," he wrote.

To clear up confusion over whether the ring was simply a Christmas gift, Hefner later tweeted: "Yes, the ring I gave Crystal is an engagement ring. I didn't mean to make a mystery out of it. A very merry Christmas to all."

This will be the third marriage for Hefner, star of E! reality series The Girls Next Door, which chronicles his life at the Playboy Mansion. He divorced Playmate Kimberly Conrad last year.
