Taylor Swift serenades Travis Kelce with songs about him as he watches on proudly

Taylor Swift wowed fans last night in Amsterdam when she surprised the sold-out crowd with a rarely played song that seemingly referenced her romance with Travis Kelce .

On July 6, during the acoustic section set, Taylor crooned a mash up of Mary's Song (Oh My My My) from her debut album, mixed with So High School from The Tortured Poets Department (which is confirmed to be about Travis), and Everything Has Changed from her beloved Red album.

At the end of the mashup, the Mary's Song section left fans going wild. The song is about a love story between two young friends as they grow up. In the hit, Taylor croons: "I'll be 87, you'll be 89 / I'll still look at you like the stars that shine / In the sky, oh my my my."

Since Taylor started dating Kansas City Chiefs tight end Travis Kelce almost a year ago, the song has been given a whole new meaning. After all, Travis' jersey number is 87, and Taylor's birth year (and 2014 album) is 1989. Travis was also born in 1989, too.

As Taylor sang the song for the first time in 16 years, the blonde beauty had the widest grin on her face. Fans have since reacted to the "Travis Kelce mega mash-up", with Swifites freaking out over the sweet declaration of love that Taylor seemingly displayed through the music while Travis was in the audience.

One person took to X to swoon over Taylor's surprise song choices. One said: "You cannot convince me the invisible string theory doesn’t work because it’s been one year since travis went to eras with a friendship bracelet and a dream and now she’s f---ing singing marys song which she wrote like 18 years ago with his football number in it."

Another person then added: "I don’t think we’re talking enough about how most of us genuinely thought she’d never play mary’s song, because it’s *that* serious to her, and she just sang it for travis."

A third then swooned: "MARY'S SONG x SO HIGH SCHOOL x EVERYTHING HAS CHANGED?!?!? THE TRAVIS KELCE MEGA MASHUP WE ARE NOT OKAY TAYLOR SWIFT IS SO IN LOVE."

And a fourth said: "I’m sobbing bc I just remembered the hidden message in mary’s song is “sometimes love is forever” and taylor singing this tonight just proves that she loves travis so much and can see them lasting FOREVER."

Taylor and Travis will soon celebrate their one year anniversary after the pair began dating following the tight end attending one of her shows in Kansas City but failing to give her his phone number.
