Actress Keira Knightley has spoken about her friendship with Sienna Miller, comparing their relationship to "two ships passing in the night".
In an interview with Glamour magazine, Knightley said that she became friendly with Miller when they filmed 'The Edge of Love' together but hadn't seen her much since then.
The actress said: "I love Sienna, I think she's a wonderful actress, but we've been like two passing ships 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 anymore."
Knightley also said: "I don't think I'm very good at figuring out female friendships. I think they're quite tricky to navigate."
