Taylor Swift fans have hilariously reacted to a mysterious shadowy figure seen watching one of her Madrid concerts from above.
When the 34-year-old pop star played the Estadio Santiago Bernabéu in the Spanish capital, a dark silhouette was spotted near the top of the stadium.
The unidentified spectator was completely alone, in a part of the sprawling auditorium that was apparently blocked off to the general audience.
Swifties flocked to social media to share their tongue-in-cheek theories about the secret identity of the enigmatic concertgoer.
Some joked that it was in fact Kanye West, who has carried on an explosive feud with Taylor for more than a decade.
