Angelina Jolie insists that her stunning post-pregnancy body is the work of genetics and breast feeding.

The mother-of-six appeared to have ditched the baby weight when she hit the red carpet for the premiere of new movie Changeling this past weekend, her first official engagement since gving birth to twins Vivienne and Knox in July.

Angie's quick transformation has sparked plastic surgery rumours but the Tomb Raider star is adamant that she is all natural.

She tells OK!, "Certain people are different in their shape. I'm breastfeeding and I think that's it.

"That's how your body naturally responds."

We're sure there's plenty of women out there who wish their bodies would 'naturally respond' in the same way...
