That takes the cake! Kim Kardashian is doused with white powder on the red-carpet as an unidentified woman pelts her with cooking flour

Kim Kardashian was left humiliated tonight when she was doused with flour on the red-carpet.

The 30-year-old reality star was covered in the white powder after an unidentified Asian woman pelted her with the powdery substance at an event where Kim was promoting her new perfume line True Refection at The London Hotel in West Hollywood.

Kim was dressed-to-the-nines upon her arrival, wearing a black blazer, leather trousers and a bright blue blouse.

Kim's whole back and hair was covered in the substance, which was later determined as cooking flour, according to TMZ.

The website reports that after the attack, Kim, who arrived at the hotel with her mother Kris Jenner, was ushered into a private room where she removed her doused jacket and brushed the flour off the rest of her outfit and brunette locks.

The reality starlet opted to go back to the event following the fracas, and the assailant was arrested by police who were called to the scene, according to TMZ.

The fire department was also called to the scene to inspect the substance, which they determined as cooking flour.

Moments before the assailant launched their attack, Kim was blissfully unaware of what was to come, happily posing for pictures and doing interviews with the press.

The attack may have quite possibly have come from a protester opposing Kim's love affair with fur.

In November Kim was the target of a PETA campaign.

Jovial: Kim was having a ball on the red-carpet prior to the ordeal joking around with photographers

The animal rights group posted a billboard in Los Angeles that featured a photo of the curvy star wearing a fur-trimmed jacket.

A picture of two foxes was included, along with the caption: 'Kim: These babies miss their mother. Is she on your back?'

The attack comes just a few months after somebody made an attempt to flour bomb Kim's best friend Jonathan Cheban in New York City while he was with Kim, near her boutique Dash last December.

Another unknown assailant attempted to throw flour in Cheban's face after exclaiming: 'This is for Kris Humphries!'

Support: Kim was accompanied to the event by her mother Kris Jenner

Immaculate: Kim's make-up and brunette locks were groomed to perfection before she got hit

Cheban and Kim ex-husband Humphries had a notoriously rocky relationship, which was played out on Kim's reality show: Kim and Kourtney Take New York.

'I think it's pathetic that someone would go to this length to show their support for someone,' Cheban told Us Weekly following the ordeal. 'With fans like that, who needs enemies?'

Humphries representation also released a statement at the time denying that Humphries had any involvement.

Kim and Humphries notoriously split up last year after just 72 hours of marriage.

'(He) would never condone hateful and unacceptable behavior like that to anyone, in any situation,' it said.

The aftermath: White powder can be seen covering the red-carpet following the ordeal

Tonight Kim little sister Khloe immediately took to Twitter to express both her outrage and praise for her sister's dignified reaction after the flour pelting.

She wrote: 'I'm proud of how Kim handled the situation.'

She then later added in defense: 'I wish I was with my sister tonight. I bet you that woman wouldn't have dared tried a thing...'

Furious: Kim's little sister Khloe took to her Twitter account to leap to Kim's defense

Meanwhile: Today Kim's younger sister Khloe was seen arriving at LAX airport and her older sister Kourtney was seen shopping at Ralph Lauren in Beverly Hills
