Harry Potter star Emma Watson has broken up with her long-term boyfriend William Adamowicz.

Speaking to the Sunday Mirror, a representative for the 23-year-old actress, said: ''Emma and Will separated last summer and are no longer in touch.''

According to reports, Watson's hectic film schedule was the reason for their break-up as she tries to find the balance between her education, personal life and movie career.

An insider previously said: ''Emma is in demand with Hollywood directors but has so much to focus on with her studies, that she has had to pass on a few things - she simply can't do ­everything.

''It's tough but she believes it was the right thing.''
