Uma Thurman

Scarlett Johansson thinks Uma Thurman has the perfect body.

'The Black Dahlia' star - who has recently hit out against the current trend in Hollywood for skinny actresses - admits she was blown away by the 'Kill Bill' star's amazing physique when she first saw her on the big screen.

However, Scarlett, 21, acknowledges she will never be able to look like her idol because they have such different physiques.

She told Cosmopolitan magazine: "I'm never going to look at Uma Thurman and hope I have her body. I'm not built like that."

Scarlett also insists women care too much about what men think of their appearance.

She said: "Men, what do they know? They don't know if you lose or gain five pounds. They're oblivious to those kind of things. A lot of men will say, 'I like you the way you are.' If they're attracted to you, they're attracted to you."
