Taylor Swift kicks off UK Eras shows as some fans wonder if singer is ready to say ‘So long, London’

Taylor Swift fans enjoy parsing the singer-songwriter's lyrics for references to her romantic life and insights into her state of mind.

But the pop superstar's fans in the U.K. didn't have to listen closely to her latest album, "The Tortured Poets Department," to get the sense that Swift had soured on the country's capital city after long making it a regular hangout and then her second home.

As Swift brings her blockbuster Eras Tour to London's Wembley Stadium this weekend, some Swifties therefore are wondering if they are witnessing the beginning of an extended goodbye.

London isn't ready to see her go. The area around Wembley was transformed for the shows, with fans posing in front of a giant mural of the singer and traveling stairs christened "Swiftie Steps" and other tributes.

Swift announced that 88,446 people were in attendance at Friday's show in what she called "the most exhilarating city in the world." Among the famous attendees: Prince William celebrating his 42nd birthday at the show and posing for a photo with Swift along with two of his children, Prince George and Princess Charlotte.

Swift gave fans a wink and a nod toward her London life during one of her two solo acoustic surprise songs: a piano medley that opened with the London-set "The Black Dog" and segued into "Come Back, Be Here" and then "Maroon."

In addition to this weekend's shows, Swift will return to Wembley for five more in August to close the tour's European leg.
