Boy Wizard Grows Up: 'Potter's' Radcliffe Arrived Drunk to Set of Blockbuster Franchise

Former child stars often take dramatic steps to prove their all grown up.

For Miley Cyrus, that means participating in racy photo shoots and announcing to the world her love of marijuana.

Actor Daniel Radcliffe is fessing up about his hard-drinking ways while promoting his first post-“Harry Potter” feature, “The Woman in Black.”

Turns out the fictional boy wizard was knocking back more than a few Coca-Colas before arriving on the set.

I have a very addictive personality. It was a problem. People with problems like that are very adept at hiding it. It was bad. I don’t want to go into details, but I drank a lot and it was daily – I mean nightly,” Radcliffe said to British celebrity news magazine Heat earlier this week.

“I can honestly say I never drank at work on ‘Harry Potter.’ I went into work still drunk, but I never drank at work. I can point to many scenes where I’m just gone. Dead behind the eyes,” the 22-year-old actor said.
