With her latest movie G.I. Joe still doing a killing on the box-office, it looks like there really is no stopping sexy star and supermodel Sienna Miller from dominating the world. That after she recently posed for the cover of the September issue of men’s magazine GQ.

In the photoshoot, Ms Miller turns over her leather outfit as The Baroness for more comfortable clothes showing off even more skin. The cover features Sienna in a very immaculate shot wearing a white ensemble with her legs getting most of the attention.

Other photos show the supermodel frolicking in the greenery with a horse and not much clothes on.
