Daniel Radcliffe has said that he came out in an allergic reaction the first time he put on Harry Potter's iconic glasses.
The 21-year-old revealed to author JK Rowling in a special video for 'Harry Potter and the Deathly Hallows: Part 2' that his glasses caused him problems when he first had to wear them.
He said: "We put the glasses on and eventually we realised I was allergic to them.
"I was allergic to the Harry Potter glasses because these two rings of whiteheads and spots had come up around my eyes. It took us about a week to realise that it was actually the glasses."
Rowling replied: "It's lucky neither of us believe in signs, isn't it?!"
'Harry Potter and the Deathly Hallows: Part 2' is released on Blu-ray and DVD on December 2.
