Kim Kardashian is covered in flour during arrivals at the "True Reflection" Fragrance Launch at The London West Hollywood on March 22, 2012 in West Hollywood

*Kim Kardashian got attacked by a bag of flour in West Hollywood.

The reality star was walking a red carpet Thursday night when an unidentified woman pelted her with a plastic bag of white powder, according to sheriff’s deputies. It landed mostly on her jacket and hair.

Paramedics were called to West Hollywood’s London Hotel, but Kardashian refused treatment, reports the Associated Press. It was later determined the substance was cooking flour.

“That probably is the craziest, unexpected, weird thing that ever happened to me,” Kardashian told E! News. “Like I said to my makeup artist, I wanted more powder and that’s a whole lot of translucent powder right there.”

A non-criminal battery report was taken by police, and Kardashian, 31, is not pressing charges, says AP. Afterwards, she reportedly went to a room in the hotel, cleaned herself up and changed outfits.

After the incident, Kim’s sister Khloé Kardashian Odom tweeted : “I wish I was with my sister tonight. I bet you that woman wouldn’t have dared tried a thing.”

Deputy Peter Gomez says that after the alleged assaulter was detained by hotel security, she was released at the scene.

Kardashian was at the London to launch her new fragrance, True Reflection.
