Katy Perry walked into her “Charlie & The Chocolate Factory” themed birthday party wearing a pretty simple white dress. But when she came out, she was covered in paint — and Russell Brand.

Here’s Katy before the onslaught of neon colored paint. Doesn’t she just look lovely?

She had all of her guests show up wearing white for the event, which was held at The Beach on Sunset in West Hollywood.

One source said, “They were totally loved up. Katy was having a ball and Russell was catering to her every whim. At one point he was down on his knees bowing and offering her a huge swirly lollipop. She grabbed it from his hands and pretended to knight him with it.”

Among the invited guests were Taylor Swift, Zachery Levi, several Oompa Loompas, and some guy that looked utterly bored.
