Booty pinching, international adventures and tons of goofing off could only mean one thing. The boys of One Direction sure know how to kick the summer off right! Today, which marks the first day of summer FYI, well, today the 5-some debuted the next trailer sneak peek for their 3D movie, giving us even more reason to get excited about the release of 'This is Us' on August 31st. Harry introduces the clip saying that when they go somewhere completely new, it's really exciting -- this is followed with behind the scenes footage from 1D's visit to Japan, as they figure out how to eat miso soup and meet some new fans. But the portion of the trailer that we know you're really going to love follows Harry as he visits the bakery he used to work at in England before he was a global star. And even back then Harry was always surrounded by adoring women -- but these lovely ladies are just a tad bit older than your normal Harry Styles fan, but just as dedicated. In fact, Harry introduces one woman named Barbara who he says used to QUOTE 'pinch my bum on a Saturday,' to which she answered 'yes I did.' It's ridiculously adorable. Later in the clip we see a nearly naked Liam trying on wardrobe and a ton of shots of all of the guys acting silly and goofing off, even while camping..
