British actress Rachel Weisz was determined to shape up after giving birth, so she could strip off for a new movie role. The Mummy star welcomed her first son with filmmaker Darren Aronofsky in 2006 and immediately set about shedding the pounds so she could bare all in upcoming movie Agora.

And Weisz had no qualms about the naked scenes, even refusing a body double to step in for her.

She tells Britain's The Daily Mail, "It was all me, (I) never even thought of using a double... I was thinking about baby fat but I think most of it had gone by the time I went before the cameras."
