"Today I begin my 26th year of freaking out over stuff," wrote the singer to caption the pic in which she is seen with agape mouth as a child.

The "Bad Blood" hit maker is expected to have a quiet birthday owing to the fact that she was on a whirlwind world tour to promote her album "1989," New York Daily News reported. Launching the tour in Japan on May 5, the singer hosted spectacular shows in 53 cities across 11 different countries, often performing several days in a row.

Throughout the tour, Swift managed to keep her fans on their toes by including surprise guest singers. Some of the celeb singers who performed in her tour were Selena Gomez, Justin Timberlake, Nick Jonas and Mick Jagger, Music Times reported. Gigi Hadid, Kobe Bryant, Chris Rock and Ellen DeGeneres are among other A-listers who also made a surprise appearance in her tour.

The tour was ended with a group hug of Taylor and her crew members from her 125-membered dedicated team. "Farewell, 1989 World Tour," wrote the singer to caption the love-filled pic.
