According to reports, Playboy founder Hugh Hefner and his fiancée Crystal Harris have set a date to tie the knot.

A magazine, UsMagazine. com has quoted that a Playboy rep has confirmed that the couple will wed on June 18 at the Playboy Mansion.

Hefner, 84, is reported saying, "It will be intimate with a close number of friends here at the mansion. No big blowout affair and something very personal."

Harris, 24, is hunting for the perfect wedding gown and is said to be eyeing a strapless dress by designer Romona Keveza.

Hefner proposed Harris on Christmas Eve last year, and gave the bride an impressive round-diamond engagement ring on Twitter.

According to an insider, the couple has set the guest list of at less than 300 people. According the sources, one person who will not be attending the wedding would be Hefner's ex-girlfriend Holly Madison. She claimed that if even if she were invited she would not be going.

Madison told Shuter, "I feel like the attention should be on them. It should not be about ex-girlfriends showing up and what are their reactions and stuff like that. I think it should be about them".

Madison also said, “Crystal hasn't been around very long -- she's a mysterious character. No one knows much about her”.
