Sienna Miller has joined a host of other fit Hollywood ladies that play leather-clad superheros on-screen.

The actress will be fighting crime in a sexy all-in-one leather suit in her new film GI Joe: Rise of Cobra.

Sienna plays a butt-kicking raven-haired baroness and she's badass and sexy rolled into one.

The Factory Girl star is almost unrecognisable as she totes a gun in a poster for the action flick - which hits cinema next August.

So we've taken a look back at some of the sexiest leather-wearing lovelies including Kate Beckinsale, Alicia Silverstone, Angelina Jolie, Halle Berry and Jennifer Garner.
