Taylor Swift sang "Karma is the guy on the Chiefs coming straight home to me" for the 13th time to celebrate her boyfriend's 13th show since the couple went public in September.

Travis Kelce watched the three-plus-hour show from a Veltins-Arena suite on night two in Gelsenkirchen, Germany. She sang for a second time "Labyrinth," which includes the line "oh no, I'm falling in love again." Swift sang the "Midnights" track in Buenos Aires, Argentina, the day before Kelce attended the show as her boyfriend.

Kelce has seen the Eras Tour in Argentina, Australia, Singapore, France, England, Ireland, Netherlands and Germany.

According to TravelMath.com, a direct flight from Gelsenkirchen to Kansas City, Missouri, is 9 hours and 44 minutes. Germany is seven hours ahead. While there's no word whether Kelce will attend the third show in Gelsenkirchen, he could conceivably make it to work on time. If Kelce left at 1 a.m. Saturday after the concert (which is 6 p.m. Friday CT), he would arrive in Missouri around 4 a.m., giving him a handful of hours before he has to check in.

TravelMath.com said, "This assumes an average flight speed for a commercial airliner of 500 mph, which is equivalent to 805 km/h or 434 knots."

London appearance: 'Do not drop the baby'

Kelce shocked the in-person Wembley Stadium crowd and tens of thousands of others watching livestreams on June 23 when he joined dancers Kameron Saunders and Jan Ravnik on stage. In a tuxedo, Swift's boyfriend carried her collapsed body to the bright red lipstick couch to revive her, put "color into her face" with a blush brush, did the Dumb and Dumber dance and engaged in a comedy bit encouraging the singer to perform her final "Tortured Poets" hit "I Can Do It With a Broken Heart."

"The one thing I told myself is, 'Do not drop the baby,'" the tight end said on the season two finale of his podcast "New Heights." "Do not drop Taylor on your way over to this damn couch. The golden rule was, do not drop Taylor. Get her to the couch safely.'"

Kelce said he joked with Swift about appearing on one of the "Blank Space" light up bicycles that her backup dancers ride during the "1989" hit.

"She started laughing," he told his brother Jason. "She was like, 'Would you seriously be up for doing something like that?' And I was just like, 'Are you, what? I would love to do that. Are you kidding me?'"

Kelce teased to fans, "You guys will have to keep showing up to the Eras Tour to see if I pop out of the stage or whatnot." He has yet to make a second appearance.

'It's a love story' (Eras Tour Version)

On July 8, 2023, a determined Kelce walked into the Arrowhead Stadium in Kansas City with a friendship bracelet he hoped he could put on the singer's wrist. The beaded jewelry had his number on it.

Long story short, that never happened and two weeks later, he called out the Eras Tour star on his podcast, "I was disappointed that she doesn't talk before or after her shows, because she has to save her voice."

By putting Swift on blast, she reached out. To celebrate Kelce's one year Eras Tour anniversary, the Kansas City tight end went to the final night in Amsterdam with his best friend Patrick Mahomes and Mahomes' wife Brittany. Swift performed a five minute mashup of her songs "Mary’s Song (Oh My My My)," "So High School" and "Everything Has Changed."

"Mary's Song" includes 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," which is significant because as a teenager in Nashville, Swift wrote a song with the numbers 87 and 89. Kelce's jersey number is 87 and 1989 is the name of her fifth album.

Swift has 16 more European shows left in Germany, Poland, Austria and the United Kingdom before taking a two-month break. She will finish her record-breaking tour in Vancouver, Canada, on Dec. 8.
