Harry Styles has melted the hearts of his fans following a sweet moment he shared with a gay concert-goer and her mom.

Yesterday, Mckinley Mcconnell took to Twitter to share a video of the moment she got the 'Watermelon Sugar' singer to help her come out to her mom in the middle of his concert in Milwaukee.

She captioned the clip: "A moment that will actually be with me forever. thank you for creating a safe place for me. thank you for letting me grow along side you as a fan. thank you for helping me know who i am. thank you. [sic]"

McKinley, who was standing near the stage, had been holding up a large banner with the words: "My mom is in section 201. Help me come out??"

Needless to say, the bold sign caught Harry's attention and the 27-year-old was happy to deliver the message to his young fan's mother, who was sitting in a different area in the arena.

So, the former One Direction singer began calling out Lisa's name in order to pinpoint her. He eventually spotted her and then went back to McKinley to give her the opportunity to make her special announcement using his mic.

Harry asks McKinley: "What would you like to tell your mother?"

When McKinley appeared unnerved by the sheer number of people at the concert, Harry decided to step in and make the announcement himself.

He shouts over to the mom: "Lisa, she's gay!"

Fans of the 'Sign Of The Times' singer have since taken to social media to share how touched they were by the coming out - and the manner in which it was enacted.

One person tweeted: "As someone who doesn’t know if she’ll ever be out to her parents this whole interaction was heartwarming and made me cry. I am so proud of you and happy for you."
