Hugh Hefner, 84, Engaged to 24 Year Old Playmate

Hugh Hefner, the founder of Playboy magazine, says he's engaged to a Playmate again.

Hefner, 84, announced his engagement to 24-year-old Crystal Harris last night on Twitter.

"When I gave Crystal the ring, she burst into tears. This is the happiest Christmas weekend in memory," he tweeted.

When Twitter followers questioned whether the ring was merely a Christmas gift, Hef clarified, "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 would be the third marriage for Hefner, who divorced Playmate Kimberly Conrad last year. He was also married to Mildred Williams. The pair divorced in 1959.

Harris, who was the December 2009 Playmate, did not comment on the engagement. But she did post on Twitter this morning, "Hef and I are TRENDING on @twitter!!!! WOW!!!"

The couple began dating nearly two years ago.

When asked if he had plans to propose last April, Hefner said it was a possibility.

"It's certainly possible," Hefner told E! News. "I certainly care enough for herI certainly love her enough. We'll see. All I want is for the relationship to be as happy as it is."
