Actress says she's nothing in comparison
The actress reckons she’s one of the most beautiful women in the business.
‘Keira is just ravishing in every way, a goddess, and I adore her,’ she says.
‘There’s no kind of rivalry. It’s Keira Knightley, you bite the bullet, you just deal with it.’
And Sienna, 26 – who stars with Keira in the movie The Edge Of Love – says she’ll never match up.
‘There’s not enough make-up that can put you anywhere near that level,’ she tells OK!
‘But she is such a cool chick and she is so bright and lovely.’
