(Cover) - EN Star Style - Emily Blunt only ate pizza for three weeks after making The Adjustment Bureau.

The 27-year-old British actress portrays ballet dancer Elise Sellas in the upcoming thriller about a ballerina and a politician who fall in love but are affected by mysterious forces.

The already-slender star had to look the part for the movie, and so embarked on a gruelling health food regime to lose weight. Emily got so sick of plain, calorie-free food though, that after filming she went on a junk-food splurge.

Lettuce, rabbit food, poached chicken and salmon... When I finished the movie, I didnt eat anything but pizza for three weeks straight, out of defiance, she laughed in an interview with Total Film.

The gorgeous star also had to train hard to get her body in peak physical condition, and admits there were tears of pain after her gruelling sessions in the dance studio. The hard work paid off though, as Emily looks like a fully fledged ballerina in the movie, which also stars Hollywood actor Matt Damon. (C) Cover Media
