It takes more than flour to break up the Kardashians.

Khloe Kardashian is lashing out at animal-rights organization PETA after a person with ties to the group dumped flour on sister Kim on the red carpet of her fragrance launch last week.

PETA has denied any involvement with the incident, but a rep for the organization told CNN in a statement that they could back the woman if she desired their aid.

Khloe Kardashian vented her feelings on her official blog Monday, writing, "Bullying and harassment is NEVER a solution and I won't be a part of any organization that thinks otherwise."

The reality star posed for a controversial nude PETA campaign in 2008.

PETA responded with a statement saying that Khloe Kardashian was, "Defending her sister, and we know she has a good heart, so we wish her well. We just wish she also had more influence on her sister."

The flour attack was a response to Kim Kardashian's frequent use of fur clothing.
