Katy Perry went home, and this time she brought John Mayer. The couple not only took a tour of the the town, The Old Mission -- but they also reportedly took a museum tour, explored the Mission grounds, the cemetery and the Mission Church. According to Us Weekly, they tried to go in and out of the town as incognito as possible. A source said, "It was just the two of them walking around at their own pace, just normal behavior. Later, the couple visited the Santa Barbara Mission Archived Library, where Mayer chatted up librarians about the local history."
