If you tap “Sandra Mittica” on facebook you will find two accounts. Personally, I think the first one is the real Sandra and the second one (with number at the end of url) is made by some anti-fan to post those stupid messages about Ville and then post their screenshots all over the web.
Why do I think so ? Because it doesn’t seem real now, it’s just came too far. I can not believe Sandra would post so rude messages about her boyfriend and that Ville is not so stupid to let her doing this.
