Playboy's Hefner Gets Engaged

Hugh Hefner, the founder of Playboy Enterprises, announced a Christmas engagement with his current girlfriend and former Playmate.

“When I gave Crystal (Harris) the ring, she burst into tears,” he posted on Twitter. “Yes, the ring I gave Crystal is an engagement ring.”

Harris, 24, was Playboy Playmate of the Month back in December 2009.

Hefner, 84, is known for his love life and has been married twice before, both times ending in divorce.

He told Fox News in November that human beings are not meant to be monogamous.

“I think that monogamy is something that has been invented along the way to take care of children,” he explained.

Playboy's stock has fallen from a high of $32.19 on April 30, 1999, to a low of $1.25 in November 2008.

It now trades at just over $5. Its recent gain has been helped by Hefner's offer earlier this year to buy the rest of the stock that he doesn't already own. The board of directors is still considering the offer.
