From showbizspy.com:

Sienna Miller says Keira Knightley is “ravishing”.

Miller — who stars alongside Knightley in new flick The Edge Of Love — reckons the pint-sized star is one of the most beautiful women in Hollywood.

Sienna says, “Keira is just ravishing in every way, a goddess, and I adore her.

“There’s no kind of rivalry. It’s Keira Knightley, you bite the bullet, you just deal with it.”

Sienna, 26, also said there is no way she can compete with Keira in the looks department — no matter how much make-up she applies.

She adds to Britain’s OK! magazine, “There’s not enough make-up that can put you anywhere near that level.

“But she is such a cool chick and she is so bright and lovely.“
