Harry Styles' tour is literally called the 'Love on Tour' so it's no surprise that couples are popping the question front left, right, and center during his concerts.
But the latest proposal caught on camera has gone viral because of its unique proposal.
After spotting a sign, that some think read 'help me propose', in the crowd, Harry went over to 'Carl' to have a quick chat.
"Can I sing two lines to my girlfriend?" Carl asked Harry. After some tossing and turning saying "I'm not sure personally..", Harry eventually gave in and handed the mic into the crowd towards Carl.
Carl then stole the show, singing Elvis' classic Can't Help Falling In Love in front of the entire crowd, shocking even Harry.
"Damn!" Harry can be seen mouthing, looking up at the screen before walking back towards the couple in shock.
As the crowd joined in for the final lines, Carl then got down on one knee to ask his partner Marianna to marry him. Then and there, the romantic fan stole the show.
What an absolute romantic gesture from the fan and how sweet is Harry to support their fans on their special day!
