Harry Styles fans express concern during Wembley gig as he braves 37°C heatwave

It seems as though Harry Styles was feeling the heat while running around Wembley Stadium on Friday (26 June) night.

Temperatures teetered staggeringly close to 38C in the UK capital and the Grammy-winning singer struggled to disguise the impact it had on him during his performance.

Fans have been sharing their concern for Styles, 32, after footage that has been circulating online appeared to show him hit the deck during the gig in London.

Video shared on social media shows the former One Direction star gallivanting along the stage during his final song of the night, 'As It Was'.

He often dashes up and down the stage to give fans a good look at him from varying angles during his shows, but this particular sprint appeared to take it out of him more than others.

His weariness was no doubt down to the sweltering heat that has been sweeping the UK, amid the brought record-breaking temperatures across Europe.

Wembley Stadium announced that fans of Styles attending his Together, Together tour would be allowed to bring metal or hard plastic water bottles into the venue due to the heatwave, while sun cream stations were also set up.

He's got five gigs left of his 12-night run at Wembley, during which he has been supported by Shania Twain, and it seems he was truly tested by the temperatures on Friday.

The 'American Girl' hitmaker was seen running down the stage ahead of performing his notorious 'whale' spit with a bottle of water that he seemed reluctant to let go of.

Styles took a swig, had a little boogie and then appeared to choke on the liquid, as he was seen spluttering on stage.

He then grabbed another bottle of water, completed his trademark spitting stunt and collapsed to the floor in fatigue after putting his all into his performance.

Cameras then showed the Don't Worry Darling actor trying to regain his composure while lying down as he continued to cough.

Styles then promptly got back on his feet and ran towards the crowd to give them a wave, before bidding farewell to fans and exiting the stage.

Although he seemed to have recovered after his brief lie down, fans of the singer have been expressing their concern for how he is coping with the physical demand of touring in such extreme temperatures.

One person said: "I was genuinely worried for a sec!"

Another wrote: "Everyone cheering but he was clearly struggling to breathe, bless him."

A third pointed out: "People forget he literally has asthma, it's not parasocial to worry about him."

A fourth commented: "I nearly had a heart attack watching the live stream!! Thought he collapsed from heat or exhaustion!!!"

And a fifth chimed in saying: "I thought he passed out."

An admirer of Styles who was among the crowd at Wembley on Friday told the Daily Mail that the heat was overwhelming in the stadium, leaving the singer 'soaked in sweat'.

The concertgoer told the publication: "After the first two songs, he took off his jacket and his shirt was already soaked with sweat, and he was like, ‘Oh god look at that! I’ve only done two songs!’"

LADbible has contacted Styles representatives for comment.
