Miss Katy Perry !

Katy Perry threw a colourful birthday party this weekend, which saw her guests covered head to toe in paint.
The singer left her 25th birthday covered in splashes of paint, but new boyfriend Russell Brand did not look so amused in his ruined jeans and T-shirt.
Katy had asked all her guests to dress in white for the Charlie And The Chocolate Factory-themed party but did not tell them they would be doused with neon paint before the night was over.
Her actor boyfriend Russell Brand, and country singers Taylor Swift and Julianne Hough, were among the A-list celebs in attendance. Besides, there were also the likes of JoJo and Perez Hilton. ;D !
