Actress Anne Hathaway has push back the date for her upcoming nuptials because of work commitments.

It looks like The Devil Wears Prada star has had to move her summer wedding date to later this year or even possibly next year according to the Mail on Sunday.

Hathaway has been dating Adam Shulman since 2008 and he popped the question late last year.

However Hathaway has been busy shooting the upcoming Batman film The Dark Knight Rises, which is set for release in July, as well as working on the movie adaptation of Les Miserables, for which she is sporting a new cropped hairstyle and slimline figure.

A source tells the publication: "Anne's worried there won't be time to get back in shape and grow her hair for a summer wedding. She also has to promote her movie Batman. They are thinking about postponing until later this year or maybe 2013."
