What's Bradley James like in real life?

I think he's an amazing actor and I was so sad Merlin ended and it would be amazing to meet him, but what is he like to meet in real life? Is he really as nice as he seems o is he just really chilled and does he get annoyed if loads of fan go up to him etc. I wouldn't want to piss him off because he is just a person like everyone else and I wouldn't want to bother him if it annoys him

:D xx
