Actress Scarlett Johansson is as famous for her voluptuous figure as her screen performances.

But the producers on the set of her latest movie, The Other Boleyn Girl, have been struggling to contain her curves on celluloid.

The star's sweet tooth and her love of British pubs caused her to pile on so many pounds that a number of scenes had to be reshot for the movie, which features Star Wars actress Natalie Portman as King Henry VIII's second wife Anne Boleyn and Scarlett as her sister Mary.

"There was some reshooting," says a source. "The problem was that Scarlett piled on weight during filming and there was concern that she looked thin in some scenes and heavier in others."

The 22-year-old American, right, was recently voted the sexiest woman in Hollywood.

She developed a weakness for British fare during filming in Cambridgeshire this summer.

"Scarlett looks sensational in the movie, but the problem has been that her weight has gone up and down like a yo-yo because she likes her food.

"She's a fan of British pubs and she really tucks in so it was a case of tightening the corset stays."
