Sienna Miller found it difficult to see herself alongside Keira Knightley in the movie The Edge Of Love – because she felt chunky and less attractive.
Having to beef up for her role as Caitlin MacNamara, the wife of poet Dylan Thomas, made her self-conscious.
'I was actually pretty nervous about acting alongside Keira because my part required me to put on weight,’ she says.
‘I just stuffed my face for the months that we were in production. I had huge fry-up breakfasts, pasties for lunch and lots of toasties.
‘Then I had to face seeing myself alongside Keira, who is the most beautiful woman in the world.’
But Sienna, 26, says her image fears didn’t stop her becoming best pals with Keira, 23.
‘We totally bonded on the movie and it was so amazing to find a girlfriend in the business,' she tells Elle.
‘In Hollywood they don’t know what to make of us because we both drink, smoke and eat.’
