Harry Styles: Horrifying scenes as global pop star chokes and collapses to ground mid-performance in London

Harry Styles has sparked concerns among fans after he appeared to choke on water before collapsing to the floor of a stage during a performance in London on Friday night.

The pop star was rocking out on-stage at his sold-out Wembley Stadium show to global hit As It Was when he abruptly stopped dancing and began coughing into a closed fist.

Video circulating online shows the music icon sporting a blue button-up shirt and tie paired with navy shorts as he guzzles water from a bottle before performing his signature “whale moment” where he spits the liquid out of his mouth and into the air.

Clutching his chest, Styles then collapses down to the ground as fans can be seen filming the incident on their phones.

The 32-year-old stayed laying on the floor for several seconds as he appeared to struggle to catch his breath.

After thumping his chest in what appeared to be an attempt to clear his throat, the pop star eventually stood up, waved to the crowd and carried on with the performance.

Worried fans took to the video’s comment thread to express their concerns for the former One Direction star.

“I was looking around in pit super confused because I was seeing him from the back. [I was] genuinely concerned,” one fan wrote.

”When he fell to his knees, my heart stopped in shock. Harry is incredible, it surely takes immense strength and stamina to perform in these temperatures, and yet he always gives it his all,” a second person said.

Another added: “I nearly had a heart attack watching the live stream! Thought he collapsed from heat or exhaustion! Love you dearly Harry!”

The incident occurred during his sold-out Wembley residence, which had been taking place amid a severe UK heatwave, with temperatures in London reaching 37C.

A red health alert was issued by The UK’s Health Security Agency to warn people in the area the sweltering conditions posed a “risk to life for even the healthy population”.
