Just days before the release of the last Harry Potter film, Daniel Radcliffe announced that he'd been teetotal for some months.
While Daniel is close to his Potter colleagues, Emma Watson recently admitted that she didn't know he'd ever struggled with alcohol.
She told chat show host David Letterman: "To be honest, it's really not something that I genuinely know much about.
"But as far as I know, he never took a sick day. He was like the most professional, amazing guy ever."
When David asked the 21-year-old about her experience with alcohol, Emma was at a loss for how to reply:
"I mean, yes, I have tried spirits! Of course, I've tried spirits," she admitted.
"I mean err, there are substances, whiskey... I'm dying here."
The actress who played the conservative character of Hermione in Harry Potter was recently pictured looking a little less than sober at a premiere afterparty.
She insisted: "We drink at 18 in the U.K.!"
Emma then added: "But I'm actually legal to drink now in the US. It's worth mentioning, I'm 21!"
Despite her obvious desire to move of from the topic, the Tonight Show host persisted until she exclaimed:
"Yes I have been drunk once in my life, as everyone does.
"I've got drunk, I've been drunk and I'll bow to that."
