Sienna Miller worried about her beauty

Sienna Miller is racked with insecurities about her body - she fears she’s losing her good looks as she heads towards 30. The British beauty dons a skintight leather outfit in upcoming action film “G.I. Joe: The Rise of Cobra,” but admits she tries to cover up in real life.

The 27-year-old actress says, “I’m lucky I’ve got a good metabolism. I’m very grateful for that. But I’m not toned at all. I think I’ve reached an age at 27 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 quite firm and tiny and, as I hit 25, things started to change. Now I’m 27 I’m noticing more changes - bare legs at the top and back is not a pretty sight. I’m lazy and if I wear clothes, it’s hidden well. I don’t feel like a beauty icon. I get pretty insecure and have the same insecurities as everyone else - sometimes more because there is more focus put on me.” (WENN)
