Actress Anne Hathaway has pushed back her plans for a summer (12) wedding because of her work commitments, according to a U.K. report.

The Devil Wears Prada star has been dating Adam Shulman since 2008 and he proposed to the actress late last year (11).

Hathaway has been busy shooting upcoming Batman film The Dark Knight Rises, which is set for release in July (12), as well as working on the movie adaptation of Les Miserables, for which she is sporting a new cropped hairstyle and slimline figure.

And Hathaway's busy schedule has forced her to reassess her wedding plans, reports Britain's Mail on Sunday.

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."
