Daniel Radcliffe has been told by his girlfriend that he must be tidier around their New York apartment.

The Harry Potter star told the Daily Mail that girlfriend Rosie Coker has given him a deadline of two years to be like a fully-functioning human being around the house.

Radcliffe admits that he doesn't cook well and leaves the house messy. Coker has helped him to clean up his act. I have made it my mission to improve myself. There's certainly progress to be made, he added.

Coker has just finished working as a production assistant on Snow White And The Huntsman, starring Kristen Stewart and Charlize Theron. Radcliffe and Coker, both 22, met on the Harry Potter set and have been close for more than a year. Both have also worked in The Woman In Black together. The film is based on the ghostly thriller written by Susan Hill. Radcliffe is also starring in a Broadway production of How to Succeed in Business Without Really Trying.

While the Harry Potter star and his girlfriend don't get to spend a lot of time together because of their work commitments, they are determined to make a success of their relationship.
