Katy Perry is taking this one-eyed thing too far!
Maybe that was the purpose of her doing it in the first place; to make a fool of those who really have it due to the experimental genetic injections ?
Before I read Xpan's comment, I was going to jokingly say that she has vax caused Bell's palsy a la Justin Bieber although his condition apparently is Ramsay Hunt syndrome, a rare viral condition that has caused paralysis in his face. Whether it's for real or she's just pretending/exaggerating, there's not enough video to know. Or it could just be an artifact of her MKUltra programming. The first comment to the tweet says it too:
Just a normal robot programming glitch!
