Socialite Kim Kardashian has laughed off the incident of a woman throwing white powder at her, calling it the "craziest" moment of her life.

"That probably is the craziest, unexpected, weird thing that ever happened to me. Like I said to my make-up artist, I wanted more powder and that's a whole lot of translucent powder right there," Kim told eonline.com.

Her sibling Khloe took to her Twitter page after hearing of the drama and declared: "I wish I was with my sister tonight. I bet you that woman wouldn't have dared tried a thing..."

The reality TV star was the guest of honour at a party for her new fragrance, when a woman threw white powder at her as she posed for pictures. She was escorted to a private room to dust herself down and later returned to the party.
