Kim Kardashian got more than she bargained for when she hit the red carpet Thursday in Hollywood.

According to the Los Angeles Sheriff's Department, the reality-show star was doing interviews outside the London Hotel in West Hollywood when a woman walked up and doused her with what the police report referred to as "powder." The substance was reportedly believed to be a bag of cooking flour.

The unidentified woman was detained by the hotel’s security and held until authorities arrived.

Meanwhile Kardashian reportedly went to her hotel room for about ten minutes, where she removed the flour from her clothes and hair and returned to the red carpet.

The famous businesswoman did not wish to press charges against the woman but police still filed a non-criminal battery report.

Paramedics were also called to the scene but Kardashian refused medical attention.

In fact, she sort of laughed the whole thing off.

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

Kim’s family, however, wasn’t so amused.

Her mom Kris Jenner, who was also walking the red carpet at the time of the attack, told E! "If anybody comes at me with something, call security."

Khloe - who was not at the event - tweeted, "I wish I was with my sister tonight. I bet you that woman wouldn't have dared tried a thing..." She also said,"What a low blow to flour bomb someone. You care that much?"

Kourtney had this to say, via Twitter: “Classy to flour bomb my sister at her charity event helping women. I wonder if they would have dared thrown the flour at my hormonal and pregnant self!"

She added, "That's my sis! ... Kim was a true professional with her reaction. She's a better person then me. I would chased her myself and beat her ..."

The woman who threw the powder on Kim Kardashian was later released.

Kardashian had been at the hotel to promote her new True Religion perfume.
