John Mayer, Skrillex & More Dress Up For Katy Perry's Haunted Birthday Party At Magic Castle

by Alex Gilman · October 22, 2012

Statistically speaking, about 75% of us have already had our birthdays this year. How were your birthday parties? Oh, you had an ice cream cake? That's cool. I think Katy Perry might still have you beat, though. Sure, we already knew she was capable of tricked-out, celebrity-packed parties, but by taking advantage of her birthday's proximity to Halloween, we think she might have climbed into truly epic territory with a costume party guests like Neil Patrick Harris and Mia Moretti took very seriously.

As these photos from Rony's Photo Booth of Friday night's throwdown at The Magic Castle prove, when even John Mayer is impressing you with his creativity, you've got something special on your hands.
