Samantha Ronson and Lindsay LohanSam Ronson's rushed to Lindsay Lohan's aid.

Li-Lo was pelted with a flour bomb for wearing what appeared to be fur.

And now her girlf is on the defensive...

Sam wrote on her My Space blog: "The girl who threw (the flour) acted like an animal herself.

"I take that back, it's an insult to animals to group her in with them, my dog is FAR more civilised than that person."

She added: "I think there are plenty of families that could have used that flour for a meal. Nice job, lady."

This all stems from the incident where a Peta supporter lobbed flour over Li-Lo in Paris at the weekend.

Sam continued: "It's a pity that some groups feel the need to assault people as opposed to fighting with words.

"Whenever I feel the need to vent about something that feels unfair to me I reach for my computer, I don't run out of the house with abusive intentions. I don't expect everyone to react the same way, but I do expect people to respect each other."

Crikey, Sam seems pretty upset.
