Daniel Radcliffe's booze battle
Harry Potter star celebrates a year of sobriety
Radcliffe has admitted he's teetotal and gave up alcohol in August 2010 as he had become too reliant on it.
"There were a few years there when I was just so enamoured with the idea of living some sort of famous person’s lifestyle that really isn’t suited to me" he said in interview with GQ magazine.
The 22-year-old also let slip that he has a mystery girlfriend.
"I’m actually enjoying the fact I can have a relationship with my girlfriend where I’m really pleasant" the star said.
