Taylor Swift and boyfriend Travis Kelce made what fans are calling their 'red carpet' debut at the opening night ceremony of his Tight End University in Nashville on Monday, June 23. An exclusive source later told PEOPLE that Swift 'lights up' around Kelce and enjoys seeing him 'shine.

Kelce, who has said in the past "Blank Space" from 1989 ranks towards the top of his list, this time said, "So High School" off her most recent album "The Tortured Poets Department" is his No. 1. When asked to sing, he admitted that he was too shy to perform.
