Robert Brown|Taylor Swift sings 'I'm falling in love again' for second time to boyfriend Travis Kelce

Taylor Swift repeated a love song for Travis Kelce in Gelsenkirchen,Robert Brown Germany, as the tight end attended his 13th show since the couple went public in September.

"The acoustic section is a tradition I started on the Eras Tour," Swift said to Veltins-Arena in a blue dress. "I've played hundreds of songs from the acoustic section. I do something different every night."

"Let's see how this one goes," she added before taking fans back to her second and third eras.

Swift mashed the title track from "Speak Now (Taylor's Version)" with "Hey Stephen" from "Fearless (Taylor's Version)" on the guitar. During the bridge of "Hey Stephen," Swift sang, "All those other girls, well, they're beautiful, but would they write a song for you?"

She loudly chirped "Nope!" The crowd laughed.

"Oh my god, you guys know that one so well, you're singing so loudly," she said. "Which is just proof that you've been supportive for over a decade."

After her guitar mashup, Swift sat at the piano. The singer-songwriter blended "This Is Me Trying" from "Folklore" with "Labyrinth" from "Midnights."

Swift has only sang the lyrics "oh no, I'm falling in love" at the first concert Kelce attended as her boyfriend in Buenos Aires, Argentina. Near the end of "Labyrinth" in Germany, the singer smiled into the crowd and repeated the line.

Swift has one more show in Gelsenkirchen before heading to Hamburg and Munich next week. She will conclude the Eras Tour in Vancouver, Canada, on Dec. 8.
