We just can't keep up with Sienna Miller's fash and beauty marathon for her global tour to promote G.I Joe. But it was rather fitting that at the Hollywood premiere Sienna came over all vintage Hollywood starlet on us. Channelling some seriously sexy Veronica Lake waves, a golden California girl tan and crimson lips, Sienna looked every inch the 40's film sex bomb. Sienna, keep up the good work, we're loving it!
