A number of the 24-year-old singer's fans shared pictures from their special day on social media, reported E!Online.
According to the posts, the handpicked fans, who had no idea what was about to happen, met at a church where they were checked by security before being escorted to the 'Red' singer's home.
They were then fed pizza as well as fresh-baked cookies and other treats before the Grammy-award winning artist arrived with her cat Olivia Benson in hand.
Swift also explained the album's personal significance and revealed the inspiration behind each and every song.
