Sienna Miller and Keira Knightley are eating loads of curry to fatten up for filming, according to a report.

The stars are currently on location together in Wales working on The Edge Of Love and have apparently been asked to work on their curves.

A source told the Daily Mail: "Keira was told to beef up for the role and she and Sienna have both been having food competitions to see who can eat the most.

"Both Keira and Sienna have bigger appetites than many of the men on set. At the moment they are on a curry diet where they have curries for lunch and dinner, and eggs Benedict for breakfast."
