From iafrica.com:

Keira Knightley admits she has lost touch with her ‘The Edge Of Love’ co-star, Sienna Miller.

The 23-year-old actress, who plays Vera Phillips in the World War II drama about Welsh poet Dylan Thomas, claims that her and Sienna, who took on the role of Thomas’ wife Caitlin MacNamara in the movie, have drifted apart since the film’s production was finished.

She explained in The Daily Express: “I love Sienna. I think she’s a wonderful actress but we’ve been like two ships passing in the night recently.

“I think that’s what’s lovely but also sad about acting. You get incredibly close to people and as soon as it’s over, you don’t see each other.

“You’re away from home, it’s a very intense relationship and then it’s not there anymore.”

Knightley, whose latest film ‘The Duchess’ is due for release on 12 September, recently confessed that she finds it difficult to maintain friendships with females.

She said in Glamour magazine: “I don’t think I’m very good at figuring out female friendships. I think they’re quite tricky to navigate.

“I have lots of friends who are guys and I find that manipulation and jealousy don’t come into it as much, whereas those things can happen easily between women.”

Hey guys, hope everyone is okay! This is my first comment in this site, but i’ve been a Keira fan for ages! :)
Regarding this particular post, I know we should never judge other people, but losing touch with Sienna might be good for Keira’s image… I mean, the latest news regarding Sienna haven’t been very friendly and portray her in a very negative way…*

Hi!
I’m glad to see you comment!

I couldn’t agree more!! I didn’t like at all the latest images of Sienna…

And the Vogue cover is out and it is…(sorry Keira!) not so good, at least for me :( I can’t quite figure what they’ve done to her hair! I expected something a bit more risky and different, since it’s the September issue, but maybe it was my bad…
I haven´t seen it posted, so i’m sorry if this is a re-post… http://community.livejournal.com/keira_daily/916772.html

It’s sadly that they haven’t kept in touch for long, but I think what Keira says is true; there are some things that make a relationship with someone harder, like jealousy.

Eline: Soooooooo true sister!*
