(Cover) - EN Showbiz - Kim Kardashian has disclosed her fears about her big day and says she's scared she will fall.

The 30-year-old reality star is tying the knot to fianc Kris Humphries this Saturday in Montecito, California.

But the blushing bride told Extra TV that she is overcome with anxiety and is worried about stumbling up the aisle.

"I was so nervous to walk down the aisle by myself, for some reason I wasn't thinking, like Oh, Bruce will be there right with me,' so I was thinking, I'm gonna fall, I'm gonna faint, oh my God, my train!'"

Kim has told guests to wear either black or white, but she will definitely be wearing the virginal tone when she says I do'.

But her friend and fashion mogul Tyra Banks says that Kim is going to do something extraordinary on her wedding day.

Although the Vera Wang creation is of deep secrecy and will only be revealed on August 20 in front of her celebrity-laden guest list, Tyra gave a hint as to what to expect.

"I'll just say she's doing something I've never seen before when it comes to dresses," the America's Next Top Model host shared of the gown's design.

Kim's wedding will air on US television network E! as part of a two-part special on October 9th and 10th. (C) Cover Media
