Kardashians `put mayonnaise on their private parts`

Washington: Kim Kardashian was apparently left horrified after her sisters said that they put mayonnaise on their private parts.

In an interview on talk show `Conan`, Kim said, "Talking about putting mayonnaise on your thing is not appropriate advice," reports a magazine.

Khloe then chimed in, "Honestly, women need to know how to take care of their stuff."

Kim interrupted and said that her sisters were just joking.

"How do you know?" asked Khloe.

Kourtney then added, "People asked us, ``What does mayonnaise on your vagina do? And we said it makes it shine like the top of the Chrysler Building. And people were like, ``Why would you want a shiny vagina anyways?"
