Tearful Taylor Swift RETURNS to the stage in Brazil after fan, 23, died in extreme heat: Singer looks emotional as fans chant 'We love you' after star canceled show due to tragedy

Tearful Taylor Swift returned to the Rio de Janeiro stage for the first time on Sunday  after the tragic death of a 23-year-old fan, who succumbed to extreme heat on Friday.

Just one day after she was forced to postpone her show due to sweltering temperatures, the pop star, 33, expressed gratitude to all her attendees for braving the record-breaking heat and rain to support her.

'How lucky do you have to be to have 65,000 people dance in the pouring rain with you?' she asked the crowd. 'I've never gotten to bring a tour to Brazil before and you've been so supportive to me ever since the beginning of my career.'

Swift continued: 'I love you so much and I'm so happy to see your faces tonight you have no idea.' Later on during the singer's set, the crowd erupted after 'Champagne Problems' as Swift teared up mouthing 'I love you,' according to social media footage.

After performing her hit, Champagne Problems on the piano, she looked emotional and teared up as the audience erupted in applause. 

In response to the tears, she mouthed 'I love you' to concertgoers. 

Her second show comes as Brazil is experiencing an unprecedented heatwave and fans were reportedly not allowed to bring water into the highly anticipated concert despite the sweltering temperatures. 

On Friday, Ana Clara Benevides, 23, fainted in the front row and was given CPR by doctors at the scene but failed to revive her.

She was transported to a hospital, where she suffered a second cardiac arrest and died.

Footage from the concert shows Swift pleading with stadium staff to give her fans water. At one point during the show, the singer brought the gig to a halt and threw a water bottle into the crowd.

Benevides was taken Salgado Filho Municipal Hospital, but died soon afterwards.

In the aftermath, fans claimed that they had been banned from taking water into the venue but this has not been verified.

In a handwritten note published on Instagram, Swift spoke of her shock and announced she would be cancelling her Saturday night performance, explaining that the risks were too high for the show to go ahead.

'I can't believe I'm writing these words, but it is with her 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 by this,' she posted.

'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. 

'I want to say now I feel this loss deeply, and my broken heart goes out to her family and friends. This is the last thing I ever thought would happen when we decided to bring the show to Brazil.'

One terrifying clip shared on TikTok appeared to show Swift struggling to breathe as she temperatures in the arena soared to more than 37C. In the 11-second clip, Swift can be seen hurriedly taking seven breaths before starting another of her hit songs.

'There were people crying, people throwing tantrums, hoping it was all a lie, in short, it was terrible,' said student Victor Guimaraes, who was waiting in line again on Sunday to watch the singer's performance. 

On Sunday, news broke that a second fan died in Rio de Janerio after being fatally stabbed on Saturday. 

Gabriel Milhomem Santos was killed just hours after he attended the world-wide tour at Nilton Santos Olympic Stadium in the Brazilian city. 

The 25-year-old, who was wearing a 'Swifities' friendship bracelet, was reportedly knifed to death as he rested on the famous Copacabana beach in the early hours of Sunday morning. 

Swift megafan Gabriel had travelled to Rio from Belo Horizonte, where he was studying Aeronautic Engineering, to see the singer's show.

He was with two female cousins when the group decided to stop by the city's famous Copacabana beach to swim in the sea in the early hours of Sunday morning.

According to his cousins, Gabriel had dozed off on the sand when three robbers approached the group, and was stabbed when he suddenly woke up in the middle of the assault.

The robbers took the keys to the group's hire care and two mobile phones, but two were later arrested by police.

Two of the robbers, Alan Ananias Calvacante and Anderson Henriques Brandão, had been released from custody hours earlier after being arrested for stealing 80 bars of chocolate.

A third man, Jonathan Batista Barbosa, reportedly with 10 other crimes on his record, is still on the run.

Swift has yet to comment on Gabriel's death.
