Daniel Radcliffe's lady wants him to clean his act up -- literally! 

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." 

What exactly does this mean Radcliffe, 22, needs to do? "I think it means I have to be able to cook for myself better than I can at the moment," he explained. "And it means that I can't leave the house in a state the way I do." 

While the actor "didn't promise her anything," he joked, "I have made it my mission to improve myself. There's certainly progress to be made."

When asked whether he'd hired a housekeeper to help him clean in his NYC apartment, he told the Daily Mail his "mum [is] here and she came 'round and tidied everything up for me."

His excuse? He had two performances on Saturday of the Broadway hit How to Succeed in Business Without Really Trying, plus a Sunday matinee. 

The star and Coker, a production assistant, met on the Harry Potter set over a year ago. "She's busy, I'm busy, but we're making it work and it's good," he told the Daily Mail. "She's helped me grow up, and I love her very much."
