A word of warning to those who dream of impressing Emma Watson one day - don't mention the words 'Harry Potter'.
The Telegraph's Mandrake has revealed the chat-up line that Watson dreads the most. Asking "Are you the girl from Harry Potter?" will not get you off to a good start.
Sadly, for Emma, she might be faced with a few more nutters as she's officially back in the dating game. Mandrake also reports that Emma has recently split from her boyfriend Will Adamovicz after a two-year relationship.
On the plus side, for anyone who wants to court Emma Watson - you know what to do. Don't mention Hermione.
