Emma Watson has admitted that she sometimes struggles to communicate with her American college friends because of the 'language barrier'.
The Harry Potter actress was appearing on The Late Show With David Letterman on Monday when she admitted that she hadn't realised "quite how big the culture gap" would be when she relocated to the US from England to study.
"I thought it would just be... a few very minor language differences, but actually I find day-to-day there are things I am unable to communicate," she said on the CBS show.
"I really needed what I would call a plaster the other day. I was bleeding quite heavily and I was running around saying, 'Guys, please, I really need a plaster!' and they just had no idea what I was talking about. It honestly took about five or six minutes to work out what I wanted was a Band-Aid."
She added: "The most embarrassing one is that I had no idea - and please excuse me - that you guys call a condom a rubber. My version of a rubber is an eraser. I've done that... Very loudly asked for a rubber and people have given me strange looks. That was embarrassing!"
Watson, who plays Hermione in the magical saga, was in New York last night for the premiere of Harry Potter And The Deathly Hallows: Part 1 alongside co-stars Daniel Radcliffe (Harry Potter) and Rupert Grint (Ron Weasley).
Deathly Hallows: Part 1 opens this Friday. The Late Show airs weeknights on CBS.
