Taylor Swift sends fans wild as as she opens Cardiff Eras Tour show speaking Welsh and rewrites song to include local slang during one night only gig in the capital (video).

The singer, 34, is currently on the UK leg of her Eras tour with her latest concert at the Welsh capital’s Principality Stadium as she performed to a whopping crowd of 70,000.

Taylor kicked off the show welcoming her fans and saying in Welsh ‘Croeso i’r daith Eras!’ which translates to ‘Welcome to the Eras Tour’.

Then during a rendition of break up hit We Are Never Ever Getting Back Together she passed her microphone to a dancer who exclaimed ‘Ych-a-fi’ a Welsh term to describe something disgusting.
