Taylor Swift shares how she deals with 'sad or bad days' after foiled Austrian terror plot

Taylor Swift got vulnerable at her Wembley gig in London on Friday.

The Love Story hitmaker has been playing sold-out shows at the huge London stadium after cancelling her concerts in Vienna, Austria last week following a foiled terror plot .

During Friday's concert Taylor was left visibly moved by the crowd. After receiving a standing ovation following her performance of Evermore track, Champagne Problems , the 34-year-old songstress shared with the crowd just how much the moment meant to her.

Smiling at the crowd, Taylor said: "Not only was I recording a video in my head of that, but I guarantee my parents were just recording that on their phones."

According to PageSix, she continued: "Anytime I’m having a sad or a bad day, not only will I play the video in my mind, but I’m gonna revisit that moment a lot. Thank you so much for giving that to us."

Taylor's comments came following the foiled terror attack plot at her Vienna concert last week, seeing her cancel the rest of her gigs in the city.

Taylor was due to perform on August 8, 9 and 10 at Ernst Happel Stadium but they were axed after two teenagers were arrested on August 8.

A third man was arrested on August 9 in connection with the foiled terror plot. The 19-year-old main suspect and a 17-year-old were arrested the previous day and a 15-year-old was questioned but not arrested.

Austrian authorities said the foiled terror plot may have been inspired by ISIS or al-Qaida.

During Thursday's gig in London, Taylor also appeared to let on how she's been feeling and coping of late, following the foiled terror attack plot. According to the London Evening Standard, Taylor donned a T-shirt, which said there is "a lot going on at the moment".

Ahead of the five scheduled dates in London, Metropolitan Police commander Lou Puddefoot said officers were "well prepared".

Security has been ramped up at Wembley, with hundreds more guards being deployed around the venue and Swifties were banned from "Tay-gating" outside the venue.

The beloved tradition has seen eager fans hanging around outside Taylor's concerts ahead of the show to soak up the atmosphere.

Taylor is back at Wembley on Monday and Tuesday.
