Kim Kardashian is to invite "at least 1000" guests to her wedding.

The 30-year-old socialite – who is to marry NBA star Kris Humphries later this summer – wants her nuptials to be a huge occasion which will eventually air on one of her reality TV shows.

A source told National Enquirer magazine: "There's no location yet, but Kim is already invited at least 1000, and the list is getting longer. The original idea was to have a wedding on each coast, but she now wants one huge wedding.

"She'll probably reveal where the ceremony is. She hopes to make a huge entrance. She's having guests sign confidentiality agreements.

The brunette beauty is also hoping to follow in the footsteps of Prince William and Duchess Catherine by having a wedding that attracts the attention of the world, and she and sister Khloe have already met with designer Vera Wang on a mission to find a show-stopping dress.

The source added: "Kim and Khloe met with Vera Wang to discuss the dress. Kim wants it to be tight-fitting, with a magnificent train. And she's having diamonds embroidered on it.

"When she leaves after the ceremony, she wants everyone watching her just as she waves. Just like William and Kate!"
