Watch Taylor Swift and Fifth Harmony Perform ‘Worth It’ at Levi’s Stadium

Taylor previewed Fifth Harmony‘s appearance with kind words, lauding the guest stars for having “one of the biggest smash hit singles in the country right now” and “one of the most powerful and loyal fan bases in the world”. When the “Bad Blood” singer asked Fifth Harmony to join her on stage at her 1989 World Tour concert in Santa Clara, California, fans got to see how “Sixth” Harmony might sound!

Taylor went so far as to don matching blue outfit with Camila Cabello, Dinah Hansen, Lauren Jauregui, Normani Hamilton, and Ally Brooke. Swift fit right in with the Fifth Harmony girls, strutting her stuff throughout the dizzying song.

The Fifth Harmony members were as thrilled as Taylor herself over the surprise collaboration. That’s all the more reason one dad says he didn’t mind every penny he spent on this unforgettable experience for his daughter and himself. “She’s a really great role model”, said Elisabeth Welzien of San Ramon. Take a look at their performance below!

Taylor Swift struck a special chord on Friday night when she added five new members to her onstage squad.
