Sienna Miller's revealing toy

Sienna Miller says her 'G.I. Joe' action figure is so accurate it includes "every nook and cranny".

The 27-year-old actress - who plays villain The Baroness in the action movie, entitled 'G.I. Joe: The Rise of Cobra' - was thrilled when producers of the film asked her to pose for the doll.

But her joy soon turned to horror when she realised the figurine showed off parts of her body she would rather keep private.

Sienna said: "I got measured in this pod so the doll is exactly to scale - every nook and cranny. They showed me my bald head before it was painted on and it was me! That was weird."

While Sienna is still self-conscious, she is certain her family will be delighted with the toy.

She explained: "I'll have happy nieces and nephews at Christmas time. My Baroness doll is so flexible too. Her foot can even flex 360 degrees. Kids will be killing me though because I'm the baddie!"

Sienna previously revealed she was "terrified" of handling guns in the new movie.

She looked so worried when she held a pistol she was taken aside by film bosses to make sure she was alright.

Sienna is quoted as saying: "It was scary. I got taken away from the group! They said, 'Sienna, you're a villain in this film and you look like you're terrified of the gun.' And I said, 'I am!' But we were shooting live ammunition that could kill someone."
