A concerning video of Taylor Swift seemingly gasping for air at her Eras Tour show in Brazil has been shared online.
On Friday night (November 17) , the 33-year-old hitmaker performed on-stage to a sold-out crowd at Rio de Janeiro's Estádio Olímpico Nilton Santos stadium.
Temperatures soared in the Latin American nation, with Brazilian media reporting that the capital city hit a record-high heat index of 59.3 degrees Celsius (139.5 degrees Fahrenheit), as reported by Reuters.
Tragedy also struck the tour, after 23-year-old Ana Clara Benevides died after waiting hours for the concert to begin.
Now, shocking fan-filmed videos are now circulating on social media and reveal the 'Bad Blood' musician seemingly struggling to breathe right after singing 'Bejeweled' at the end of her hours-long performance.
Watch the moment below:Many people expressed their concerns for the artist on the social media platform, with one fan writing: "OMG… this breaks my heart in so many levels. She’s so professional but watching her like this, my best wishes go to her."
"I’m also thinking about fans that had to endure those crazies [si] temperatures… take care people and stay healthy!" the post continued.
A second user chimed in: "Oh my god my heart dropped I thought she was gonna faint," and a third added: "She still pushed through it while helping everyone else up I feel so bad I love this woman so much."
Despite struggling in the sweltering heat, Swift was a good sport throughout the concert and paused her set several times to urge stadium staff to give water to those in the crowd who were chanting.
She even took matters into her own hands by handing out bottles of water to desperate attendees during her 'All Too Well' performance.
The videos were shared before Swift announced on Instagram that Saturday's (November 18) show would be postponed out of consideration for the "safety and well-being of [her] fans, fellow performers and crew".
The decision came after Ana Clara Benevides sadly died after she arrived at the stadium to watch the hitmaker perform, per Brazilian newspaper Fohla De Sao Paolo.
In a heartbreaking final video, Benevides documented her journey to the venue, showing herself waiting in line for hours to get a good spot in the general admissions area of the stadium. But once she was in, she reportedly fainted and was assisted by a team of emergency workers.
T4F - the concert organizers - shared in a statement on Instagram that a medical team transferred her to a hospital but "after nearly an hour of emergency assistance, she regrettably died".
The late fan's cousin, Estela Benevides, told the outlet that Ana ultimately passed from cardiorespiratory arrest, however, no official cause of death has been reported as of this writing.
Benevides' tragic death took place before the 'Love Story songstress kicked off her show at around 7:30PM local time, per BBC News. The Sun reported that Ana was declared dead at 8:50PM.
The singer later took to social media to mourn the tragic loss of her young fan, writing: "I can’t believe I’m writing these words but it is with a shattered heart that I say we lost a fan earlier tonight before my show.
"I can’t even tell you how devastated I am by this. I’m not going to be able to speak about this from the stage because I feel overwhelmed by grief when I even try to talk about it."
She added: "I want to say now I feel this loss deeply and my broken heart goes out to her family and friends."
Our thoughts continue to go out to Benevides' loved ones at this time.
No further information has been revealed about Swift's concert on Sunday (November 19).
