Scarlett Johansson and Josh Hartnett’s relationship is rumoured to be in trouble because the two are so busy with their respective filming schedules that they never have a chance to see each other properly - and when they do, they argue.

Scarlett is currently filming The Other Boleyn Girl in the UK while Josh has been in New Zealand working on 30 Days of Night.

A source close to the couple told the New York Post: “They are on the rocks. Scarlett is always mad at him, and they are always arguing.”

Scarlett also said recently that she doesn’t want her career to be constrained by a relationship: “Life can get very complicated when you travel the world. I don’t want my private life to determine whether I take a part and go far from home.”
