Keira Knightley claims Sienna Miller is her 'inspiration'.

The actress - who filmed ‘The Edge of Love' with Sienna earlier this year - insists it was 'amazing' to work with her fellow British star and she was 'blown away' by her talent.

Keira, 22, said: 'Working with Sienna was amazing. She was great. She came in at the last minute to replace Lindsay Lohan - literally in a week. She blew me away.

'I love her. She's hilarious and a good actress. I didn't really know Sienna before - we'd met a couple of times and chatted, but I loved working with her. She was a huge inspiration.'

Keira - who was just 16 when she shot to fame in ‘Bend It Like Beckham' - also insists she doesn't take her success for granted and has refused to let her superstar status go to her head.

She said: 'The trouble is that fame goes up and down. If you're aware of the fact that it might all end tomorrow, you don't live like it's not going to. A lot of people get that first burst of success and think, ‘Well, this is me forever', which is fair enough. I don't necessarily believe my way is the better way - it's just how I choose to make it work.'
