Twilight actress Kristen Stewart and musician John Mayer are lucky enought to be on the guest list for Katy Perry's Birthday party.
The Firework singer chose a rather daring vampire outfit to celebrate her birthday in style. Katy's party was held in Los Angeles on Friday night and celebs in attendance included Twilight actress Kristen Stewart and on-again-off-again boyfriend John Mayer.

And to celebrate her 28th, Katy wore a Halloween inspired vampire outfit while boyfriend John opted for a prosthetic nose and chin to go with his zombie hunter outfit.
Kristen was reported to have enjoyed every minute of the A List party as she chatted away to friends. However, the actress was there without her on/off boyfriend Robert Pattinson, and instead partied the night away with his best friend Marcus Foster. However, although Kristen appeared to have enjoyed herself, she was dressed in her usual clothes rather than embracing the fancy dress code.
Costume or no costume, Kristen was probably eager to have a few drinks and unwind after dealing with the trauma of her first live interview since the whole affair scandal. Fans definitely did not like the fact that she cut her web chat short, with one even telling her to 'go to hell'.
