Seriously? OMG! WTF?

Katy Perry/Instagram

Katy Perry is in the midst of her Las Vegas residency, and celebrities are flocking to see her.

This weekend, Paris Hilton, Kim Kardashian, and Sia were in the audience. And all we got was this photo of the four of them.

Normally. Sia has her face covered with a wig. But the one time she doesn’t is the one time she should’ve. I mean, she is better than those publicity whores. At least, I thought she was.
