Harry Styles is no stranger to showing his solidarity with the LGBT community on stage, and the former One Direction star put on another touching display of support during his solo show in London last night (April 11).
The 'Sign of the Times' singer, 24, was praised by fans on Twitter after proudly flying two rainbow flag during his set at a packed-out O2 Arena.
Harry's show of LGBT support came just weeks after he debuted a new song, 'Medicine', which fans heralded as a bisexual anthem after its lyrics alluded to hooking up with boys.
The flags weren't the only sign of acceptance in the room, though: Thousands of fans also lit up the arena in rainbow colours during Harry's performance of 'Sweet Creature'.
Fans lit up their phones in rainbow colours after a campaign organised by a group called Rainbow London Project, who told Metro the stunt had taken three months to prepare.
Organisers cute out 14,000 pieces of coloured paper ahead of the gig, before handing them to attendees with instructions to hold them over the phone camera lights during the song.
The result was something to behold...
THANK YOU TO EVERYONE WHO MADE YESTERDAY HAPPEN🌈❤— Rainbow London Project (@RainbowHProject) April 12, 2018
