Kim Kardashian said to be excited by 'wedding of the century'

Kim Kardashian's wedding cake is set to be similar to Prince William and Duchess Catherine's, and sources claim the star wants to make her imminent wedding the "biggest TV wedding of all time".

The reality TV star will tie the knot with NBA player Kris Humphries on August 20.

And Kardashian has insisted on lavish nuptials right down to the 10-tier white cake, with chocolate-chip icing and black-and-white decorations which she hopes will resemble the traditional multi-tiered fruitcake with cream and white piping designed by British baker Fiona Cairns for the royal wedding.

A source said: "Kim wants it to resemble Prince William and Duchess Kate's!"

Kardashian previously revealed she wants her wedding to be much more extravagant and spectacular than when Prince William married Catherine Middleton at London's Westminster Abbey on April 29.

A source added: "Kim is planning the wedding of the century. She doesn't see why a royal wedding should get more attention that hers. She sees herself as a bigger celebrity than Kate Middleton."

The nuptials are set to be shown on TV in a two-hour special and Kardashian thinks it will prove more popular than William and Catherine's wedding.

The source added: "Kim thinks it would probably be the biggest TV wedding of all time."
