Los Angeles: Pop star Taylor Swift continued her tradition of bringing surprise guests for her tour stop by performing with Fifth Harmony.
During a concert at Levi's Stadium in Santa Clara, California, Swift invited Fifth Harmony to join her on stage and together they made a live duet, reported Ace Showbiz.
The 25-year-old "Blank Space" singer went so far as to don matching blue outfit with Camila Cabello, Dinah Hansen, Lauren Jauregui, Normani Hamilton, and Ally Brooke.
She collaborated with the girl group on their single "Worth It" and performed the choreography.
"Sound check with @fifthharmony right after they taught me their choreo and before they lent me one of their outfits so we could all be twinzies," Swift posted a picture from the rehearsal before the show.
Meanwhile, Fifth Harmony has just released "I'm In Love With a Monster", a song recorded for "Hotel Transylvania 2" soundtrack. Adam Sandler, Andy Samberg, and Selena Gomez will return for the second movie due September 25.
