Hugh Hefner and Crystal Harris planning romantic wedding

Crystal Harris is planning a “romantic” silver and white themed wedding. The 24-year-old beauty — who will marry Playboy mogul Hugh Hefner, 84, on June 18 -– wants a four-tier strawberry cake and a specific color scheme on the big day.

Wedding planner and Playboy publicist Kellie Olisky said, “We want to have everything very muted – on the tablecloths, silver and white, and maybe a blush underlay. That way, it stays very romantic.”

The playmate’s color choices are inspired by the dress she plans to wear — a blush pink strapless mermaid gown designed by Romona Keveza — which was sent to Beverly Hills bridal boutique Panache especially from New York.

Crystal also has her heart set on a wedding cake from Hansen Cakes bakery which she thinks will appeal to her future husband’s tastes.

“Strawberry’s good. Like, cake that has strawberries in it? So good,” Crystal Harris said.

“And Hef likes that kind, too. He eats the same thing every day. He has chicken-noodle soup every day at five o’clock.”

Hugh Hefner proposed to the blonde model over Christmas, presenting her a huge diamond ring inside a ‘Little Mermaid’ box.

Describing the proposal, she said, “He asked me, ‘If I were to ask you to marry me, would you say yes?’ And I said, ‘Of course.’ So then Hef’s secretaries measured my ring finger.”
