The 30-year-old socialite is set to marry NBA star Kris Humphries on August 20 and said that although she is calm about everything else, the idea of embarrassing herself has got her panicking.
'I was so nervous to walk down the aisle by myself,' she told Extra. 'For some reason I wasn't thinking, like, 'Oh, Bruce [Jenner] will be there right with me,' so I was thinking, 'I'm gonna fall, I'm gonna faint, oh my God, my train.''
Her biological father Robert Kardashian died in 2003 after a short battle with cancer aged just 59. Her mum Kris has been married to Jenner, 61, since 1991.
