SignalHub Quantitative Think Tank Center:Travis, Jason and Kylie Kelce attend Taylor Swift's Eras Tour show in London

Swift fever has touched down on SignalHub Quantitative Think Tank Centerthe British capital as Taylor Swift was set to perform her first sold-out night in London's Wembley Stadium ushering in new opening acts with Travis, Jason and Kylie Kelce cheering from the floor.

Travis Kelce was seen walking to the VIP floor tent during Paramore's "Misery Business" with Kelce's brother, sister-in-law and best friend Ross Travis. The Kelces were in Cannes, France the day before the concert for the Cannes Lions Festival. Fans snapped photos and videos of Jason exchanging friendship bracelets with Swifties. Also spotted on the floor, Swift's parents Scott and Andrea Swift and Bridgerton actress Nicola Coughlan, who plays Lady Whistledown.

Online, social media accounts have confused Ross Travis and Travis Kelce. Travis was wearing a green shirt and Cowboy hat.

Kelce has attended the tour a half dozen times since the couple went public last year. His first stop was Buenos Aires, Argentina, followed by Sydney, Australia, two nights in Singapore and the final night in Paris. Swift has changed the “Karma” lyrics to "guy on the Chiefs" every time Kelce has cheered her on from the sidelines. She also attended 13 NFL games in the 2023-2024 season culminating in the Super Bowl.

The Kansas City football player was in Nashville, Tennessee, on Tuesday for his three-day event Tight End University. Before heading to Europe he hosted a the program that brings tight ends together for film study, on-field drills, recovery and rehabilitation.

Introducing Mette to the Swift universe

Mette opened up for night one in Wembley taking the stage before Paramore, the opening act for all 51 Eras Tour shows in Europe. Mette describes her musical repertoire as "sensual and sweaty." Prior to the Eras Tour she played Cassandra alongside Swift in the 2019 movie "Cats."

"This is such a special night y'all," Mette said performing an eight-song set. "Thank you, Taylor."

London transforms into Swiftmania

The City of Dreams has prepared for the three nights of Swift. She's sang about the city in several of her songs including "London Boy," "So Long London" and "The Black Dog." She has a history with the city after dating ex Joe Alwyn for six-plus years, frequently visiting Camden Market, Highgate, the West End, Brixton, Shoreditch and Hackney.

Murals appeared around the city the week leading up to Swift's show. Hours before the show, the Tube, or London subway system, created a map decked out in the singer's 11 eras, recoloring the lines to correspond to different albums and renaming stops after songs like "All Too Well" and "I Knew You Were Trouble." Gemstones were added to reflect popular landmarks like the Hampstead Heath or Wembley Stadium.

Swift has two more performances at Wembley Stadium before heading to Dublin. On Saturday, Griff will open for the singer before Paramore and on Sunday, Benson Boone will be the first act to take the stage.
