Harry Styles is currently on his London tour where he will be performing at Wembley Stadium for the next few nights. And fans spotted one thing at his gig and said he "knows what he's doing"13:22, 22 Jun 2026Harry Styles fans have been treated to a twelve-night run at Wembley Stadium, with every evening bringing something slightly different.‌The 'Together, Together' tour, which has come after Harry's latest album 'Kiss All The Time, Disco Occasionally,' seems to be going down a treat with superfans, who are heading to the stadium in their droves, clad in sequins, ready to see Harry Styles in the flesh. Plus, they also get to see mega-star Shania Twain as well, who is singing her hits such as 'Man! I Feel Like A Woman!' and 'That Don't Impress Me Much'.‌However, fans of Harry have been left asking the same question after one of his performances, wondering what he was doing.‌Becca, who posts on TikTok as @concertbecca, shared a quick clip of Harry singing his hit 'Kiwi' to the tune of 'Watermelon Sugar'.In the comments, a woman wrote: "My sister was at the front with this sign! I like to think she is the reason."Content cannot be displayed without consent‌The sign read: "My son was born to Kiwi! Please play it." And he seemed to come through for her!Another person penned: "The way he's singing songs from all his albums, including a mix of 1D songs, is like, this may be his last tour, maybe he'll be settling down after this."But people had similar questions, as they were confused about something he'd done over the Watermelon Sugar track.‌"Why’s he rapping it and six sevening through it, I'm crying," a fan penned. Someone said they were "f****** crying laughing" at the comment, because it did look like he was doing the 6-7 motion.What is 6-7?Children have been saying 6-7 in a (highly irritating) sing-songy voice which has left both parents and teachers feeling exasperated. When belting out the digits, kids often move their hands back and forth like weighing scales, and it's a viral trend that doesn't seem to be going anywhere.The nonsensical trend likely stemmed from lyrics in a Skrilla song called Doot Doot (6 7). It then became linked to a 6ft 7in basketball player called LaMelo Ball.‌The soundbite went viral on YouTube and has since taken over social media. As it stands, there are millions of posts on TikTok that use the 6-7 hashtag.So the next time you hear someone say 6-7, you can be safe in the knowledge that it actually means nothing, and it's just a silly trend.But in the clip, it looked as though Harry Styles was moving his hands like a weighing scale, with someone joking: "He's one of us."Article continues belowAnother showed a screenshot of him laughing to himself, with a fan writing: "He knows exactly what he's doing!" as he's known for being very unserious with a wicked sense of humour.
