Sienna and Keira help each other out

Sienna Miller has revealed she leans on her good friend Keira Knightley in times of stress.

The British actresses became close when they starred with each other in Dylan Thomas film 'The Edge Of Love'.

“I think we keep ourselves afloat,” she told Parade.com.

“If things happen in the press that are hard to deal with or you give in to that awful temptation to occasionally Google yourself and be mortified at what people can write about you.

“It’s hard to ignore it. Keira will phone me up. She’s like: ’I’m thinking about doing it’.

“I’m like: ’I am, too, but don’t do it’. And we’ll kind of talk each other out of it.”

She added: “We talk about what you talk about with any girlfriend, just what’s going on in your life.

“She gives me good advice and hopefully vice versa.”
