For whatever reason, the wonderfully down to earth and unapologetically herself Billie seems to attract the most random fan theories in the biz, and this latest one is a true head-scratcher.
Settle in team, because this one's pretty wild.

There is a cluster of Billie fans out there that currently believe the "Bad Guy" singer is a member of the 'Illuminati'. For all of you who don't know what and who the Illuminati is, it is a group that is said to be made up of powerful elites (Beyonce is their Queen) that secretly control the world we live in and are hell-bent on bringing about new world order.
Oh, by the way, there is no proof that the Illuminati even exists, it's really just another conspiracy that has been allowed to run wild over the years (kind of like the whole 'Neil Armstrong never landed on the moon' thing).
Put simply fam, the Illuminati is preposterous (although compelling).
Just Billie, wielding her Illuminati power
So why do fans now thing Billie is in this ultra secret/elite group?
It all comes down to the apocalyptic type imagery Billie uses in her music videos, specifically for "All Good Girls Go To Hell".
Since the music video dropped, fans have been tweeting about the 'connection'.
