Crystal Harris plans 'romantic' wedding to Hugh Hefner

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 colour 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 colour 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.

Crystal told New Yorker magazine: "Strawberry's good. Like, cake that has strawberries in it? So good.

"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 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."
