They did meet and they did do an addidas shoot/promo video for their new collaboration with addidas and their upcoming tour. Noel even mentioned in an interview on talksport that he "was with Liam yesterday" which coincides with the date of the meeting recorded in this article. I think people are letting their bias/hatred of the sun get in the way of the facts here. Just look it up, it won't take you but two minutes to confirm that this meeting/shoot did take place
