Kim Kardashian was left red-faced last night when she was flower-bombed on the red carpet.

The 31-year-old was hosting the launch of her own new fragrance, True Reflection at the London Hotel in West Hollywood when the humiliating incident happened. Within minutes of Kim's arrival, an unidentified Asian woman threw a bag of cooking flour over the reality star, covering her hair, black blazer, blue top and leather trousers in white.

A shocked looking Kim immediately rushed off the red carpet in embarrassment. According to TMZ, Kim was ushered into a private room where she cleaned the flour off of her clothes, face and hair.

Putting on a brave face, Kim decided to go back to host the event and the woman was arrested by police shortly after.

Kim laughed off the incident, telling E! Online: "That probably is the craziest, unexpected, weird thing that ever happened to me."

Like I said to my makeup artist, I wanted more powder and that's a whole lot of translucent powder right there."
