Taylor Swift fans were left mystified on Saturday after mysterious figures were seen dancing on top of Wembley Stadium on the second night of her Eras tour.

Troubled Swifties were baffled by a group of three people stood watching and dancing along to the American megastar as she took to the stage for another adrenaline-fueled night of her sell-out tour.

Videos began emerging on social media around half way through the show of the trio seemingly enjoying the singer’s performance from the vertigo-inducing spot.

Some fans claimed they were security guards or even drone spotters, while others joked they were Taylor’s former partners Joe Alwyn, Scooter Braun and Matty Healy.

But the arena later revealed the group were ‘pre-approved professionals’ who were part of the pyrotechnics team for the event.
