A blast from the past echoed through the 'Eras Tour' stage as Taylor Swift rekindled old memories, inviting her former boyfriend, Taylor Lautner, for an unexpected reunion during her concert in Kansas City, Missouri.

Friday night saw Swift debut a new video for "I Can See You," showcasing her collaboration with Joey King, Presley Cash, and Lautner. Subsequently, she welcomed the trio to the stage, eliciting cheers from the audience, according to People.

Praising Lautner, Swift shared, "During the making of the 'Speak Now' album, he played a pivotal, positive role. Every daring stunt you saw in the video was his own." Swift continued, expressing her warm relationship with Lautner and his wife, playfully adding, "Having the same first names certainly helps keep us close."

The on-stage reunion coincided with the release of Swift's re-recorded 2010 album "Speak Now (Taylor's Version)."

The surprise moment triggered a wave of excitement among Swift's fans who rushed to social media, sharing their delight over the reunion. The couple, who briefly dated in 2009, were celebrated by fans posting comparison photos of the pair hugging during their previous relationship and at the recent concert.

Twitter user @tswifterastour reminisced over the pair's past, drawing a line from their history to the night "Speak Now (Taylor's Version)" was released. Others enthusiastically tweeted their adoration for the reconciled exes, with one remarking, "The best ex reunion ever!"

Swift delved deeper into the backstory of "I Can See You" via Twitter, applauding Lautner's commitment to the video's stunts, and acknowledging the support from Lautner's wife, Taylor Dome Lautner, during the shoot. Swift also appreciated King and Cash's powerful comeback from their earlier appearance in the "Mean" video.

"I was thrilled to experiment with directing fight scenes and plot a heist storyline with my talented DP Jonathan Sela. So proud of this one," Swift remarked.

Following the concert, Lautner posted a playful photo of the trio emulating a popular "Spider-Man" meme, and captioned it with, "Secrets out! Tonight was wild."

Lautner's role as the muse behind Swift's hit song "Back to December" is widely speculated. In contrast to her earlier breakup songs, Swift revealed to Yahoo Music that this track expressed an apology, a first in her music. The lyrics, redolent with regret, were a stark reminder of their past romance, which an anonymous source suggested ended because they were "better as friends."
