Fifth Harmony has their summer tour happening presently, but Friday night they surprised the Swifties at Levi's Stadium in Santa Clara, Calif. as special guests on Taylor Swift's 1989 World Tour.

The girl group is blazing the charts with their empowering and feisty double platinum single "Worth It" so of course that's what they performed with Swift.

Prior to the group hitting the stage with Swift, the "Bad Blood" singer went through her typical guest performer spiel that they are there because they want to be and the crowd needs to be extra loud for them.

Swift even rocked Camila Cabello's spare costume, which is part of the girl group's Reflection: The Summer Tour experience so they "could all be twinzies" on stage.


Swift did the group's "Worth It" choreography too, which they taught her earlier in the day during sound check.

The girl group looked like they had a blast on stage with Swift with Swift noting one particular moment (when she was back-to-back with Normani Kordei Hamilton) "was SO MUCH FUN".

Swift shared a photo "cuddling" with Cabello and her bandmate Ally Brooke Hernandez as their stellar performance came to a close.

Swift even declared on Twitter, "I want to be in Fifth Harmony" and at least for the night she was definitely the sixth honorary member.

The girl group teased on their Instagram a short video of the magical ending of their performance and Cabello captioned that she was literally crying from being so overwhelmed with happiness.

"THAT WAS SO AMAZING," she gushed about performing on Swift's tour with her bandmates.

Cabello's gratitude for this opportunity continued to pour out on Twitter as she admitted to being a bit lost for words and deeming Swift as one of her "greatest friends".

Cabello is clearly the closest 5H member to Swift, but Hamilton, Hernandez, Dinah Jane Hansen and Lauren Jaurgeui were all grateful for the experience too.

"[T]onight was a literal dream," Hamilton beamed.

Hernandez shared similar sentiments, while thanking Swift "FOREVER" and noting just how much she loves her.

Hansen shared a series of tweets revealing she was "so nervous" to take the stage on Swift's tour and also sharing her many thanks too. Plus, she admitted it was difficult keeping her and bandmates' performance a surprise, but they did manage.

Jauregui called taking the stage on Swift's tour as special guests, "SUCH AN INCREDIBLY MAGICAL EXPERIENCE!!!"

Now we're wondering how Swift will top this special guest performance.
