WATCH WTF Is Wrong With Katy Perry's Eye?!

Katy Perry was in the middle of a recent performance in Las Vegas when she had trouble keeping her right eye open. It kept drooping and looked like a robot glitching...see video below!

People had a lot to say about it online. One person said, quote, "Her clone was glitching. That's scary."

Another said, quote, "It wasn't the eye thing that was weird it was the fact she acted like it didn't happen and went on with the show."

But others found it pretty funny. One person said, quote, "That baby doll you had as a kid with the eye that kept closing." And another compared her to a Disneyland animatronic after 10 years.
