Keira Knightley & Sienna Miller: Skinny & Skinnier!

Sienna Miller and Keira Knightley looked like they were trying to out-skinny each other at the world premiere of their new movie Edge of Love at the Edinburgh Film Festival yesterday.

With Sienna wearing a black tasselled dress by Jasmine Di Milo, and Keira in a cream Chanel jumpsuit and black Chanel cardigan, the two cut extremely slender figures on the red carpet.

Earlier this week, Keira’s mother - and Edge Of Love scribe - Sharman MacDonald hit back at persistent rumours about her “anorexic” daughter, likening the media to “playground bullies”.

"She's always been thin. She's her daddy's daughter, with his long body," she told a UK newspaper.

"It's a playground situation that we're looking at with the press - it's a form of bullying - but what can we do?"
