The 84-year-old media mogul is set to tie the knot with his 24-year-old girlfriend at the Playboy Mansion on June 18 and insists no expense will be spared to create a perfect day.
The Playboy magazine boss` generosity is covering all aspects of the big day, including the flowers, which he wants to be bold to contrast the pale colour scheme Crystal has chosen to match her Romona Keveza dress.
Spokesperson Kellie Olisky 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."
Entertainment for the evening will come from veteran musician Ray Anthony, as well as Kanye West collaborator DJ Cassidy, while Torrance Bakery is creating a special strawberry cake for the occasion.
Crystal`s two sisters and Playmate Anna Berglund will be her bridesmaids, while Hugh`s brother Keith and his sons Marston and Cooper will form the groom`s party.
The 300 guests can expect to receive their invitations, which are currently being crafted by upmarket boutique Papeterie, in the coming weeks.
Kellie added in an interview with RadarOnline.com: "The day is going to be a testimony to their love."
