Playboy mogul Hugh Hefner dead ??

Playboy mogul Hugh Hefner has become the latest victim of an internet death hoax.

A social network rumour began circulating Monday that said the 85-year-old Hefner had tragically passed away, reports contactmusic.com.

Hefner immediately took to microblogging site Twitter to scotch the rumour.

"The rumours of my death are, as Mark Twain observed in a similar situation, greatly exaggerated. I'm very much alive & kicking".

Hefner calls off his wedding with Crystal

The couple have decided to cancel their nuptials just five days before they were due to tie the knot on Saturday (June 18) at the Playboy Mansion.

According to TMZ.com, 85-year-old Hugh and Crystal, 25, had a huge argument over the phone last weekend which resulted in the blonde model moving herself and her belongings out of the mansion.

Everything had been in place for the wedding, which was to be attended by over 300 guests.

Crystal had picked a pink Romona Keveza gown to wear and the flower arrangements had been selected to match the dress. Guests were looking forward to enjoying a lavish meal, finished off with a Torrance Baker strawberry cake.

Hugh's spokesperson Kellie Olisky previously said, "No expense is being spared for the wedding. It isn't even a compromise, because Hef wants Crystal to have the wedding of her dreams. Hef asked that the flowers be bursting with colour and this will look great with Crystal's lighter coloured theme everywhere else."

Crystal's two sisters and Playmate Anna Berglund were supposed to have been bridesmaids, while Hugh's brother Keith and the media mogul's sons Marston, 20, and Cooper, 19, had been asked to form the groom's party.

Hugh has been married twice before.

He wed his first wife Mildred Williams, with whom he has two children, daughter Christie, 58, and son David, 55, in 1949 before divorcing her 1959.

He then he tied the knot with one-time Playboy Playmate Kimberley Conrad, the mother of Marston and Cooper, in 1989, before filing for divorce 11 years later, although the separation was only finalised in March 2010.

Hugh Hefner to wed Crystal in June

'Playboy' mogul Hugh Hefner has said that he is completely "devoted" to his fiancee Crystal Harris and feels fortunate to have the 24-year-old in his life.

The 85-year-old says that he can hardly wait for his third trip down the aisle with the blonde beauty, reported Contactmusic.

Hefner will marry Harris at the Playboy Mansion in Los Angeles on June 18 and Hefner insists that his new fiance is the only woman for him.

"I'm devoted to her. This is as happy a time in my life as I've ever had. I feel very fortunate," he said.

For Hefner, having a happy home life is especially important as he admits he had a strict upbringing and sought comfort in movies when he was a child.

"I grew up in the 30s and 40s. 'Frankenstein', 'The Bride of Frankenstein', I loved them. 'King Kong' was my favourite. I didn't exactly come from a home full of hugs and kisses. It was a typical conservative, puritan home and I was quite a solitary child, a bit of a dreamer. Movies showed me another world and sparked a desire in me," he added.
