TradeEdge Exchange:Taylor Swift sings love mashup for Travis Kelce in Amsterdam during Eras Tour

Taylor Swift wrapped up her final night in Amsterdam singing two never-before-performed-live songs on TradeEdge Exchangethe Eras Tour, including a love mashup for her boyfriend Travis Kelce.

"I can't believe this, but I haven't played this song yet on the Eras Tour, so that's fun," she told the audience Saturday night, holding her guitar up for the jam-packed crowd inside the Johan Cruijff Arena.

Her pink dress cascaded to the stage and she strummed her guitar. "Hit the ground, hit the ground, oh, oh," she sang, and fans cheered as they recognized the first line from "Sweeter Than Fiction." The bonus track from "1989 (Taylor's Version)" was written for the 2013 movie "One Chance."

Swift has played every song from her albums "Speak Now (Taylor's Version)," "1989 (Taylor's Version)," "Folklore" and "Midnights" during the Eras Tour.

She then mashed in "Holy Ground" from "Red (Taylor's Version)."

'I'll be 87, you'll be 89': Why the lyric is numerically significant for Taylor Swift and Travis Kelce

"OK, so you get bonus points if you know the words to this one," Swift said, sitting down at the piano, "because it's from my first album and I've never performed it on the Eras Tour."

With Kelce cheering from a suite, she sang "Mary’s Song (Oh My My My)" which has the line "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."

This is significant, because as a teenager in Nashville, Swift wrote a song with the numbers 87 and 89. Her football player boyfriend wears the jersey number 87; 1989 is both Swift's and Kelce's birth year and the name of her fifth album.

If that wasn't a clear enough love message for the Kansas City Chiefs tight end, she mashed in "So High School" − a song from "The Tortured Poets Department" that she wrote about him − and "Everything Has Changed," a love song from "Red (Taylor's Version)."

Almost one year ago on July 8, Kelce attended the Eras Tour in Kansas City. He had a friendship bracelet with his phone number on it and a dream to get it to Swift. Since then, everything has changed.

The superstar singer-songwriter has 22 more shows left in Europe. She'll have a two-month break and head to North America in the fall.
