Here's an advert for the upcoming event:

It may be a coincidence, but it's interesting that they didn't choose the ML clip for the advert but instead FS. Not that I'm complaining, she's gorgeous in this video.
But it's something non-fans would probably not pick. My guess is still that whoever had the idea to invite her is following her carrier and probably used her email adress on instagram, considering how out of the sudden this concert is happening.
Tho my therory doesn't go well with the fashion show in Publea. It's a bit odd that there are suddenly two non-dancing public appearances in 2 months. But again... I'm not complaining.
