Kim Kardashian is Ashamed!!!

Disgraced socialite Kim Kardashian still has nightmares about her sex tape scandal - because she'll always remember having to explain herself to her young stepsisters.

The pretty brunette hit the headlines last year (06) when footage of a sex romp with Brandy's brother Ray J was leaked to an internet porn firm. Kardashian tells Glamour magazine the sex tape was a little harmless fun she filmed with Ray J during their three-year romance.

She put the tape into storage when the couple split. Then, during a vacation with pal Paris Hilton, she was alerted to the fact that candid moments had been leaked and footage of her naked and having sex were online.

Kardashian admits she was horrified but the worst thing about the whole drama was having to explain what a 'porn star' was to sisters Kylie, nine, and Kendall, 11. She recalls, "One day my sisters were watching TV and a picture of my face flashed across the screen with the words 'Sex Tape?' underneath. "I was devastated.

These girls look up to me and want to copy everything I do." Kardashian's disappointed stepfather asked her to speak to the girls. She adds, "It was the hardest conversation I've ever had... Kylie admitted, 'Some kids at school said you were a porn star.' How do you respond to something like that?"
