Katy Perry celebrated her 25th birthday bash with a Charlie and the Chocolate Factory-themed White Party at The Beach Restaurant on Sunset Blvd. in West Hollywood over the weekend.

The “Hot N Cold” singer paid homage to Willy Wonka and the Chocolate Factory and donned Oompa-Loompa painted nails during an event that left guests splatted with multi-colored paint on Saturday night.

The bash was attended by Katy’s new boyfriend Russell Brand and celebrity pals Taylor Swift, Julianne Hough, and blogger Perez Hilton.
