Sienna Miller loves working on her new movie – as she’s made a “friend for life” in co-star Keira Knightley. Miller stars with Knightley in new movie The Edge Of Love, and the two girls have formed a strong friendship off set.

The Layer Cake star says, “I love Keira. She is so nice and she gets me and where I’m coming from. We always chat about how weird the public attention is and boys. I’ve found a new friend for life.”

An unlikely friendship has blossomed between co-stars Keira Knightley and Sienna Miller.

The girls, who are currently filming The Edge Of Love – a film about Dylan Thomas – together, hit the town last night with Keira’s fella Rupert Friend and their other co-star Matthew Rhys in tow.

Sienna’s boyfriend Jamie Burke was suspiciously absent, despite the fact he is in London at the moment, but it clearly wasn’t stopping Sienna from having a good time.

The gang went for dinner in Archipelago before having a very schoolkid moment of linking arms while running down the street.

In the film the two feisty, free-spirited women are connected by the charismatic poet, who loves them both.

It is understood that the script features a sexy threesome with the two women and the poet, and has been described as “very steamy” by those who have seen a sneak preview.

As we revealed earlier this week, 25-year-old Sienna stepped into the role of Caitlin MacNamara – Thomas’s wife – in the movie when Lindsay Lohan pulled out after she was asked to take a drugs test.

We’re told Sienna and 22- year-old Keira have become inseparable on the set in New Quay, Wales, so much so they are currently househunting for neighbouring cottages overlooking the sea there.

We’re told: “Sienna and Keira feel it would be great to have homes there and go on joint holidays once filming stops, so they can keep up their friendship.

The source added: “They’re actively hunting for the perfect cottages in the area.”

I think she’s prettier in print than on film… I dunno why.
