This photo of Keira Knightley and Sienna Miller last week…always a story behind every image and in this case, the negotiation process was hilarious.

When faced with photographers, some stars just wrap jackets around their heads, others get on with it, try to ignore it, Lindsay Lohan and Paris Hilton wave and invite it, Taupe Garner plays happy mommy, and Keira and Sienna front like they don’t want it but end up posing for it anyway.

So they’re standing on a street corner in London somewhere, instead of just heading to their destinations, they stop and complain, with Sienna shooting off her foul moth, reminiscent of the time I saw her at Burger King at the Salt Lake City airport. Trust me, this wasn’t an exception – every other word out of this girl’s mouth is F*ck and C**t.

The girls beg to be left alone, with Keira launching into a soliloquy about working ever so hard last week, deserving a rest, and for good measure throwing in a comment about how brilliant their movie is turning out to be. Clever, non?

After a few minutes of bartering, the two agree to do a mock walk down the sidewalk – not like a red carpet, mind you, but a “candid” pretend walk, arm in arm, giving the pappies their pictures, and allowing them to move on with their evening.

Watch how it all unfolds, especially when the cameras start flashing - the contrived way they start their promenade kills me. They love it and they hate it, don’t they?
