Sienna Miller Needed Fake Boobs For New Movie Role

Sienna Miller had to wear prosthetic boobs for her role in upcoming action movie GI Joe because her lack of curves didn't fit the part.

The actress admits she was slightly stunned when director Stephen Sommers informed her that her small chest needed an extra boost so she would look more curvaceous on screen.

She says, "(I wear a) tight black leather outfit. And much bigger boobs.

"They gave me these things that looked like chicken fillets. The director said, 'I'm gonna be honest, I like girls with big boobs', and I don't have them so we made them bigger.

"At least he's honest. But I was mildly offended."
