Adele brought her eagerly-anticipated Hyde Park gig to a dramatic halt last night after concerns were raised for a member of the crowd.
The songstress, 34, was midway through her hit James Bond theme song Skyfall when she spotted an unfolding drama in the throngs of her audience.
The quick-thinking star immediately stopped singing and cried out for security to intervene while also telling concert-goers to move out of the way.
In footage of the incident, Adele is seen waving her arms in the air to alert officers of the ensuing chaos in front of her.
"Stop, stop, stop. Security!?" Adele shouts out as her band put down their instruments.
Adele then checked on the audience member from the stage, bellowing over her microphone: "Do you need security's help?
"They're coming," she assured.
Guiding the team of medics to the guest, Adele cried out: "Right in the middle there, can you see where they are all waving?" as members of the 65,000 strong crowd began to part.
It was an emotional return to the stage for Adele who was left moved to tears at various points throughout her set.
The headline performance signalled Adele's first public performance since her cancelled Las Vegas residency.
After releasing her fourth album 30 to huge acclaim last November, Adele announced a lucrative Sin City residency at The Colosseum at Caesars Palace Hotel.
However, just hours before the shows were due to start, Adele announced in a tearful video she would have to postpone - to the disappointment of travelling fans.
The award winning singer apologised to her fans saying the residency had been “absolutely destroyed” by delivery delays and coronavirus.
Adele said her production team had tried “absolutely everything” to pull the show together in time but that it had been “impossible”.
After performing her first song on Friday night, Adele admitted to the crowd she was 'f***ing s****ing herself" to be back on stage.
Later in the evening, Adele said she was 'so happy to be back' as she became overwhelmed and fought back tears.
Adele treated the crowd, which included A listers such as Tom Cruise, to a selection of hits from her collection as well as some tracks from her latest album 30.
Throughout the night, Adele was seen sipping on a hot drink to soothe her throat after struggling with vocal issues in the past.
She was forced to cancel her 02 Arena gigs in 2017 after losing her voice.
Earlier this year, Adele faced another setback when she was forced to cancel her Las Vegas residency at the 11th hour.
Her headline set at BST Hyde Park festival was Adele's first public appearance in the UK in five years.
Taking to the stage in a black sequinned halterneck gown with her hair swept into a bun on Friday night, Adele became emotional as the audience chanted back the opening lyrics to her 2015 hit Hello.
She told the crowd “what’s happening to me” as she asked them to help carry the tune until she continued the ballad in her typically powerful fashion.
After playing her opening songs, the Tottenham-born singer said: “Hello, I’m so happy to be here.
“Guys, I’m back at home, also where I know. The amount of times I have been up there drunk off of my face, singing along to other artists at these shows.”
She added that she was “thrilled” to be back on stage but that she found it “strange to be in front of a crowd again”, which included her son and one of her best friends.
During the two-hour set she performed classics tracks and new hits including Rumour Has It, One and Only, To Make You Feel My Love, Rolling In the Deep and Easy On Me.
In her typically down-to-earth style she chatted to her fans throughout the event who had travelled from across the world and drank a mug of tea, noting she was currently not drinking alcohol.
After spotting a sign announcing it was a fan’s 18th birthday, she ensured they would have a particularly memorable day as she promised to buy them their first drink after the show.
A couple of lucky fans also received a special momento from the event as she hurled concert T-shirts along with a personalised message and a £50 note into the crowd using a T-shirt cannon gun.
Ahead of her last song, Adele appeared to refer to various delays and last-minute postponements of shows over the past year, telling the London crowd: “I know that a lot of things have happened with this album and I’m sure a lot of you feel that you’ve been let down and stuff, which is mortifying really and upsetting to me.
“But I take my singing very seriously and the last thing I would ever want to do is let people down but I had to do that, it just wasn’t right.”
To close the landmark performance she sang Love Is A Game accompanied by a spectacle of fireworks as she told the crowd “I love you so much London”.
