The British tabloids are once again predicting trouble for Lindsay Lohan and Samantha Ronson, but if the DJ's response to an animal rights activist-led flour shower of the starlet is any indication, the stuck-together squeezes remain as tight as ever.

Ronson was caught in the dusty crossfire as an apparently fur stole-wearing Lohan was splattered early Saturday morning while entering a Parisian nightclub, and she soon took to her blog to defend her inamorata and condemn the methods used by the powder-wielding PETA supporter.

"It's a pity that some groups feel the need to assault people as opposed to fighting with words. ... It seems lately I am learning that there are too many people who put another species before their fellow man and that's sad. I don't wear fur, but I don't think I have the right to ATTACK those who do. No one has that right," Sam fumed on her MySpace page. "I'm pissed at the bag of flour thrown on Lindsay last night. Not because I got powdered down, but because the girl who threw it 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 civilized than that person."

Ronson then pointed out, "I think there are plenty of families that could have used that flour for a meal. Nice job, lady."

You'll recall that Lohan was sued earlier this year by a woman who claimed she walked off with her $12,000 mink coat, which she discovered when she was flipping through a magazine and saw the actress wearing it.

Meanwhile, was the white powder attack just one of several dustups Lindsay and Sam have weathered recently?

Britain's News of the World claims that a few days before the flour ambush, Lindsay candidly shared her supposed romantic troubles with one its reporters.

"Things are very difficult at the moment," she's quoted as saying as Ronson "glared at her" from across the VIP section of a London nightclub last week. "I'm just trying to work out what to do."

The London Daily Mirror contends the duo also had a jealous spat at another hot spot, although they purportedly kissed and made up -- publicly.

"They went in for a full-on tongue sandwich, their hands all over each other," a detail-oriented spy relays to the paper. "Nobody knew where to look."

And on that saliva-soaked note, let's set the Wayback Machine for January 2006, when Lindsay reportedly decorated a ladies room stall in a New York bar with a four-letter dig directed at Scarlett Johansson.

The aspersion-casting was apparently provoked by the inexplicably sought-after affections of Jared Leto, who had segued from a romance with Scarlett to a dalliance with Lindsay, his co-star in the little-seen "Chapter 27."

For reasons unknown, the newly minted Mrs. Ryan Reynolds is discussing the incident in the December issue of Allure, professing confusion over what led her less-employable peer to label her with the foulest of female-centric profanities.

"I don't know what the motivation was," she shrugs to the mag. "I remember it was something really vulgar -- I mean shockingly so, like, 'Whoa, what, who are you?'"

It's a question she's still asking.

"I don't really know that person," sniffs Scarlett of Lindsay, who beat her out for the twin-tastic lead role in "The Parent Trap." "I only met her, like, three times."
