After Interviews in the Philippines whether he was asked if he has Filipino blood, Xander was pretty much clueless and even said, "I'll get my blood checked". The Filipino media speculated that he is part Filipino because of his family name "Eusebio" and also his Filipino characteristics such as his face and his tone as well.
In their first full concert held yesterday, Xander explained at the end part of their concert his Filipino blood, his explanation was pretty funny :))
Check out the video:
So he does have Filipino blood, since his grand father was of spanish descent from the Philippines, so Part Chinese, Part Portuguese, Half Korean and now Part Filipino :))
