Norah Jones' slim role

Norah Jones was left shocked when producers of her new movie asked her to lose weight.The 'Don't Know Why' singer - who stars in 'My Blueberry Nights' alongside Jude Law and Natalie Portman - never felt overweight until faced with the producers' request.She told Britain's Glamour magazine: "I was asked to lose a few pounds. First I got really mad, then nervous, thinking, 'Oh no! I'm fat!' "The 27-year-old - who made an appearance as herself in 2002 comedy 'Two Weeks Notice' with Hugh Grant and Sandra Bullock - says she now empathises with Hollywood actresses who are under constant pressure to be thin.She said: "It was a horrible thing to hear but I understand the game. I was just amazed that it was really an issue, and it made me have a lot of sympathy for really skinny actresses. I think they need to eat a cheeseburger!"'My Blueberry Nights' hits the screens in June.
