Reality TV star Kim Kardashian, who will marry rocker Kris Humphries Aug 20, wants a wedding cake similar to that of Prince William and Duchess Catherine's.

The 10-tier white cake with chocolate-chip icing and black-and-white decorations will resemble the traditional multi-tiered fruit cake with cream and white piping designed by British baker Fiona Cairns for the royal wedding.

"Kim wants it to resemble Prince William and Duchess Kate's!" contactmusic.com quoted a source as saying.

The 30-year-old has previously revealed that she wants her wedding to be much more extravagant and spectacular than the royal wedding which happened here at Westminster Abbey April 29.

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