Petra Nemcova wants a wedding with "a bit of craziness".

The Czech model says she and British actor Jamie Belman - who got engaged in January after eight months of dating - are still figuring out the specifics of their big day, but they want it be "lots of fun".

She said: "Part of it will be more formal and part of it will be just lots of fun and just craziness. We want a little bit of craziness."

The 31-year-old beauty - who has dated singer James Blunt and was engaged once before to British photographer Simon Atlee, who was tragically killed in the Indian Ocean tsunami in 2004 - said they might say their vows on her fiance's homeland but are still undecided.

She told "It will probably be in England, but we're still figuring out which specific place will be the best. We haven't picked just yet."

However, the catwalk beauty has decided what she will wear, revealing she has opted for a "beautiful and elegant" Marchesa gown.

Although Petra and Jamie haven't been together for very long, she was sure he was 'The One' the first time she met him.

She gushed: "Both of us knew right away. We fell in love really, really fast. He is a real man. There are no layers. He's not like an onion. He is who is. He's incredibly loving, nurturing and caring and I love that."
