Katy Perry: Willy Wonka Birthday Bash!

Katy Perry celebrates her 25th birthday with a Willy Wonka and the Chocolate Factory extravaganza at Sunset Beach in Hollywood on Saturday (October 24).

“THAT was MAGIC! I’m SO happy!!!!” Katy tweeted the next morning. “I am just giggling at random… I think this is how it will be for a while…”

Guests were required to wear white to the party and left with neon paint spattered all over them. Celebs in attendance included her boyfriend Russell Brand (pictured here), Taylor Swift and Julianne Hough. And of course there were Oompa Loompas!!! (Katy‘s custom Oompa nails from Minx Nails are pictured below.)

New York City-based DJ trio The Misshapes got the party going, starting off the night with a Miley Cyrus song — Party In The USA!

Happy Birthday, Katy!!!
