She added: "Surgery is far too frightening. I couldn't."

Although she yearns for a larger chest, Keira insists she is happy with her
slim figure and admits she regularly exercises and eats healthily to keep
fit.

The actress also hit out at society's current obsession with weight and
insists women should be happy about themselves whatever their shape or size.

She explained: "I do like to keep fit, only because I like to be able to run
around and do things. But I think it would be great if we saw a wider range
of women of all ages, of all shapes and sizes in the media."
