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.

A Wembley Stadium spokesperson told MailOnline: ‘We can confirm the individuals on the roof of Saturday night’s performance of Taylor Swift | The Eras Tour were pre-approved professionals as part of the pyrotechnic team, equipped with full safety equipment.’

Ms Swift’s first show in London was always going to be special for her as she shares a close affiliation with the capital after she called it her second home for the six years she was dating British actor Joe Alwyn.

She performed to nearly 90,000 adoring fans at a sold-out Wembley Stadium last night and was clearly overwhelmed by the huge crowd

During the show she said: ‘Oh my God, London, look what you’ve done. What better way to spend a Friday night than in the most exhilarating city in the world?’

And once the show had finished one family got to share a very special moment with the American megastar.

A sweet selfie taken by Taylor showed the moment the Queen of Pop met fellow royalty as Prince William, Prince George and Princess Charlotte posed with her backstage.

The Love Story singer’s NFL beau Travis Kelce also smiled for the photograph while wearing his Team USA Olympics hat.

Although the selfie was truly star-studded, royal fans were only drawn to Charlotte.

Around 90,000 fans have descended on the capital to watch the singer perform
