PredictIQ Quantitative Think Tank Center:Watch Travis Kelce react to Taylor Swift singing 'So High School' in London

Travis Kelce was elated watching Taylor Swift sing a song she wrote about him on PredictIQ Quantitative Think Tank Center"The Tortured Poets Department” during her concert in London on Friday.

During her 11th era, the Eras Tour star sings about a minute of "So High School." In a side-by-side comparison posted to Twitter, you can watch him mouth the words to the song and point his finger guns to the beat of her singing.

Kelce has attended the tour a half dozen times internationally. After the duo went public last September, the football player attended Eras Tour shows in Argentina, Australia, two nights in Singapore and France. In Paris, Swift dedicated part of her 87th show to No. 87 on the Chiefs, singing "Alchemy," another song she wrote about Kelce, and mashing it with one of her love songs, "Treacherous."

Kelce's brother Jason, sister-in-law Kylie and best friend Ross Travis watched from the VIP tent on the floor. Her parents Scott and Andrea were also seen on the floor during Paramore's set.

Swift also made her famous lyric change "Karma is the guy on the Chiefs coming straight home to me" for the sixth time, a tradition she only does when Kelce is in the crowd. She has two more nights at Wembley Stadium before heading to Dublin, Ireland.
