Taylor Swift stops show and shouts 'what' after being left visibly shocked during Eras Tour concert

Taylor Swift was left open-mouthed and visibly shocked during her performance in Cardiff, even stopping in her tracks to soak in the atmosphere in the Welsh capital.

The moment was sparked by the crowd's reaction to her performance of Champagne Problems. She stood for over a minute taking in the moment, looking stunned

On the big screen she was seen mouthing, "Oh my God", then took out her earpiece in disbelief at the sound of the crowd and mouthing, "What?!" She put her earpiece back, before she told her audience: "This crowd in Cardiff is one for the books. This is different - you're another level! I love you so much, thank you for that. You're just so beautiful - you're so generous to us."

Swift delivered plenty of surprises during her gig at Cardiff's Principality Stadium. Firstly, she sent the audience wild by opening her set with a few Welsh phrases, including an impressive delivery of a full Welsh sentence - "Croeso i'r daith Eras!", "Welcome to the Eras Tour!"

Then one of her dancers shouted 'ych a fi! ('gross!') later on in the show, much to the hilarity of the concert-goers. Meanwhile one little girl in the crowd was surprised with a once-in-a-lifetime experience by the megastar herself, after she gifted her the iconic 22 hat.

More than 70,000 ticket-holders were in the stadium to see the superstar for her single night in the Welsh capital. Hundreds of fans who were not lucky enough to get tickets are sitting outside the stadium listening to the show.
