Looks like it's gonna be a witch hunt, y'all! Katy Perry was in Boston the other day and what do you do when you're in Boston with nothing to do? OBVIOUSLY go to the Salem Witch Walk to learn about witches! The This Is How We Do singer was snapped with the women who work at the witchy attraction, and they totally posted about it on their Facebook! They said: 'Katy Perry participated in The Salem Witch Walk today and did a little love magic with Lorelei, Leanne Marrama, and Jody Cabot!' OOOH! How innneresting! Some 'love magic'?
