Sorry, Donald! Guess she didn't take your advice!
Katy Perry will turn 28 this Thursday, and celebrated her upcoming birthday over the weekend by combining some of her favorite things this month: Halloween spookiness and her on-and-off man, John Mayer!
The pop star had a MASSIVE costume party Friday evening at The Magic Castle in El Lay, during which she dressed up as a very SEKSI Vampire, while her man for the moment opted for some Zombie hunting threads!
And guess who else showed up for the festivities?!
