GI Joe stunner Sienna Miller catches friendly fire in mammaries.
"I burned my boobs," Miller admitted at the Hollywood preem for new actioner.
"I slipped on a rubber bullet and I was covered in bruises. But it was all funny, that’s what you sign up for."
Director Stephen Sommers took the heat for the incident and said thankfully the Birt beauty didn’t suffer any long term damage.
"We burned Sienna’s breasts, she didn’t burn them, we did it," Sommers said proudly.
"We’ve all seen them since then and they look fine."
