Singing sensation Tom Grennan was forced to call a halt to his long-awaited London gig at the O2 on Thursday.
The Lionheart hit-maker, 27, brought his first ever arena tour, What Ifs and Maybes, to The O2 - but it didn't quite go as smoothly as he planned after one fan passed out in the audience.
While performing a number of his chart-topping hits to the thrilled audience, Tom's eyes glanced down on to one poor fan who appeared to be in trouble throughout the gig.
Proving that his fans are the most important thing to him, Tom called a halt to the concert, asking his band to stop before he asked the person if they needed water.
"Do you need water? Whose got water?," before he ran off to the side to get some.

"Everybody is going mad and that. It's sweaty. Obviously it's my water bottle, but just give it to the person that has fainted," the singer instructed before throwing his own water bottle into the crowd.
Tom's gesture was met with applause from the audience and the singer went on to double check if any more of his fans needed hydrating as medics rushed to help the fan.
The Something In The Water hit-maker went on to dedicate the next song to the unwell audience member as he restarted the show.
"I hope that that person is okay right now. This song is for them," he shared.
Tom's long-awaited London show comes after the British singer was left shocked to realise that Hollywood icon Anne Hathaway is a huge fan of his.
Last month, the singer was preparing for a performance on The Graham Norton Show as the Princess Diaries actress looked on from around the corner.

Ahead of taking to the stage, Tom and his crew were rehearsing for their vocals in the hallway as Anne peeked out from around the corner as a member of his team filmed the interaction.
Tom's manager John shared the adorable footage on his Instagram alongside the caption: "When @annehathaway comes out of actual nowhere to listen to the warm-up and she's not even on the show."
Anne then appeared from behind a wall before introducing herself to Tom, explaining that she's a fan of his music after listening to him warm up for his single Here.
