I'm guessing that she's going to be present at the London Fashion week, from February 19th through 24th February. Would be strange if she was not present there, when she was still going to visit the city. She is after all one of the biggest fashion icons in Asia.
I will definitely try to get hold of cheap airline ticket from Norway to the UK. ^^ It's not often you get such a chance to meet your idol
