Keira Knightley is ''naturally a procrastinator''.

The 28-year-old beauty occasionally takes the time to be very organised about her life, but admits most of the time she puts things off until the last minute.

She said: ''I'm naturally a procrastinator. I have moments where I am very on it and then I have huge swathes of time where I feel like I am procrastinating. And this happens to be one of them right now.''

The Oscar-nominated actress has enjoyed huge success with roles in 'Pirates of the Caribbean', 'Atonement' and 'Pride and Prejudice', but she insists it's impossible to plan for achievement in Hollywood.

She explained: ''I'm totally plan-less as I've always been. I don't think you can feasibly have plans in the business because it's not in your hands. I'm not complaining - I've been incredibly lucky. I don't think you can ever second-guess yourself, either.''

Keira - who is married to Klaxons musician James Righton - previously opened up about her acting success, revealing she didn't feel she deserved it.

She said: ''It's taken me time to overcome my own doubts and insecurities. It's been my nature not to want to believe in my own success and that I don't deserve my success. But that's something I've fought to overcome.''
