Boho babe SIenna Miller isn't as crazy about her body as the rest of us are: “I think I’ve reached an age now where it’s time for me to start working out a bit. I can’t get away with it any more. I used to be able to get away with it. I was quite firm and quite tiny and as I hit 25, things started to change. Now I’m noticing more changes. You know, a top and bare legs at the back is not a pretty sight! I’m lazy and if I wear clothes, it’s hidden well.”
