Director Stephen Sommers has denied asking Sienna Miller to wear a cleavage enhancing costume for upcoming movie G.I. Joe - after the British actress was reportedly "mildly offended" by the request.

The Alfie star recently hit out at the filmmaker's insistence that she boost her assets for her role in the action blockbuster. Miller told Hollyscoop.com, "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."

However, Sommers has laughed off her comments, claiming he would never make such a demand of one of his stars.

He says, "Everybody here laughed because they know I would never say that to an actress. I guess the costume department gave her a tight fitting bra, but no one gave her rubber breasts or whatever. It is 100 per cent Sienna Miller."
