Khloe Kardashian -- PETA is DEAD to Me

Khloe Kardashian is cutting off all ties with PETA ... claiming she will NOT support an organization that condones the "bullying" art of flour bombing.

Khloe -- who has appeared on several billboards for the People for the Ethical Treatment of Animals -- says she was disgusted when she found out the organization has ties to the woman who attacked her sister Kim.

Now, she's released a statement saying, "Not only has PETA lied to the public, but they have proved that they support this kind of behavior. I’ve been a vocal supporter of PETA for a long time but I have also been very vocal about anti-bullying, so this was a huge disappointment for me."

TMZ broke the story ... the woman who floured Kim at a red carpet event last week is Christina Cho ... a major PETA activist with a history of anti-fur protesting.

Here's Khloe's entire statement:

"Hi dolls. I’m sure you all heard what happened to Kim last week (thank you SO much for the love and support you all showed her), and I just received word that the woman responsible has very close ties to PETA, despite PETA publicly stating otherwise.

Not only has PETA lied to the public, but they have proved that they support this kind of behavior. I’ve been a vocal supporter of PETA for a long time but I have also been very vocal about anti-bullying, so this was a huge disappointment for me.

As you all know, I don’t condone violence and bullying and what happened last Thursday was just that. I am absolutely disgusted by their behavior. Everyone is entitled to their own beliefs and opinions — I personally don’t wear fur but that doesn’t mean I am going to force my views on anyone else, ESPECIALLY by violating them.

I am a very proud sister right now, because Kim handled last week’s incident like a champ. She got cleaned up and was back out there in a matter of minutes. Go Kimmie!
