He's had his fair share of women over the years and only got divorced from his second wife in March.

But Hugh Hefner knows how to bounce back in love, and yesterday he announced that he is set to get married again.

The Playboy tycoon, 84, Tweeted last night that he and his girlfriend Crystal Harris, 24, had got engaged.

In the early hours of Christmas Day morning, he wrote: 'After the movie tonight, Crystal & I exchanged gifts. I gave Crystal a ring. A truly memorable Christmas Eve.'

Then last night he added: 'When I gave Crystal the ring, she burst into tears. This is the happiest Christmas weekend in memory.'

Not to be outdone by her fiancé, Crystal then took to her Twitter page to say: 'The most memorable Christmas.'

And later on, to clear up any confusion, Hefner wrote: '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.'

She also added a photograph of a present she gave Hefner, a portrait of her and him and their King Charles spaniel, which was commissioned by playmate Victoria Fuller.

Crystal was born to British parents in Arizona, who moved back to the UK after her birth, but then came back to the States a couple of years later and settled in San Diego, California.

While she was studying psychology at San Diego State University, she started modelling and was noticed by Playboy.

She met Hefner on Halloween in 2008 and started dating him in January 2009 while he was also dating identical twin glamour models Kristina and Karissa Shannon.

But he ended his relationship with the twins in January this year and has remained monogamous to Crystal since.

Crystal once said that she believes she and Hefner were able to bond because she lost a long-time boyfriend in Iraq and he was going through a break up with Holly Madison, whom he dated for 8 years.

Hefner, who founded Playboy in 1953 with Marilyn Monroe as his first cover girl, has been married twice before.

In 1949, he wed Mildred Williams with who he had two children, Christie, now 58, and David, now 55.

before their wedding, Mildred confessed to Hefner that she'd had an affair while he was away serving in the Army, so she allowed him to sleep with other women because of her guilt over her infidelity, but they divorced in 1959.

Then in 1989 he married Playboy Playmate Kimberley Conrad, who gave him two sons, Marston Glenn, 20, and Cooper Bradford, 19, but after 11 years of marriage, Hefner filed for divorce from Conrad stating irreconcilable differences, which was finalised in March this year.
