The child actor has revealed his heartbreaking news in a recent interview.
Daniel Radcliffe is known for one thing - his portrayal of Harry Potter which he lived from the age of 11 until his early twenties.
And while he is wildly successful from the magical saga, the actor has recently revealed that it wasn't always a happy time.
In a radio interview with Lauren Laverne for BBC Radio 4’s latest Desert Island Discs, the Harry Potter star detailed how his fame after the series led him to substance abuse.
"If I went out and if I got drunk, I’d suddenly be aware of there being interest in that because it’s not just a 'drunk guy' It’s ‘Oh, Harry Potter’s getting drunk in the bar.'"
Daniel said that his fame “carried some kind of interest for people and also a slightly mocking interest”, adding that it was "inherently funny for people"
"The way of dealing with that was to drink more or get more drunk, so I did a lot of that for a few years," he says.
“A lot of drinking that happened towards the end of Potter and for a little bit after it finished. It was panic, a little bit of not knowing what to do next – not being comfortable enough in who I was to remain sober.”
Harry Potter engulfed the actor's formative years and when it ended, left the young man in a spiral. He says that after multiple attempts of quitting alcohol, it was his friends and family who provided him with "enough perspective on my life" to help him through.
Daniel has been sober since 2010, and has since been in over twenty film and TV productions.
It is reported that the actor is worth $179 million AUD.
