Taylor Swift performs her sold-out Eras Tour in London for the first time post Joe Alwyn breakup

"London, look what you’ve done now," said Taylor Swift to the audience.

The 14-time Grammy winner made a comeback to London for her following sold-out Eras Tour performance, receiving a warm welcome from a crowd of 90,000 enthusiastic Swifties at Wembley Stadium on Friday.

“London, look what you’ve done now,” Swift, 34, said onstage during the first of a three-night run.

“You’ve got to see something like this to see how amazing you’re making me feel right now,” she said of the massive audience from the stage.

“That was really cool. That immediately went straight to my head. Now you’re making me feel really, really powerful.”

Die-hard fans were eagerly lined up outside the stadium hours before they were allowed in, hoping to secure standing spots by the barrier.

Maisie Holland, a 22-year-old self-proclaimed Swiftie, expressed her anticipation, stating, "I've waited for this day for so long. Me and my sister bought these tickets last year and have literally not stopped talking about it since then."

London itself has also been caught up in Swift fever, with the city buzzing with excitement. 

The singer's influence can be felt in various places, including bars and hotel lobbies like the Black Dog pub, which inspired a track on her latest album, "The Tortured Poets Department."
