'Harry Potter' star Daniel Radcliffe, 22 years old, has grown up from a child star to an adult star now and has admited that he used to have a serious drinking problem.

On the time during shooting on 2009's "Harry Potter and the Half-Blood Prince." Radcliffe said , "I became so reliant on [alcohol] to enjoy stuff."

Radcliffe said that he went cold sober last August and hadn't touched the stuff, and the paparazzi never capture him drunk.

Radcliffe also said he's not comfortable being a role model.

"I don't look at myself as a role model. I would never place myself on that pedestal, obviously. If other people want to place me there, that's up to them," he told MTV News, last year. "I would advise them not to because I don't think you should deify any human being. I think it's something that I've grown more comfortable with the idea."
