Harry Styles is set to have a massive 2017 thanks to his film debut in Christopher Nolan's Dunkirk, but some suspicious activity on social media — along with a mysterious TV spot that's hyping a certain date — indicates that there may be more to look forward to from the One Direction singer, and soon. On March 25, during an episode of the U.K.'s X Factor, a quick glimmer of a preview flashed that featured Styles, soaking wet, stepping out of a dark room and into a light-filled doorway. There's a long look at those green eyes of his, and as subtle piano plays in the background, the date is revealed: April 7. That's not all, though: Styles flooded his Instagram with ... light. Or blank space. Or maybe he just sat on his phone and accidentally uploaded a bunch of white fields to the photo-sharing app. Whatever it is, he just happened to post these non-pics as the 30-second snippet started making the rounds. https://www.instagram.com/p/BSE0QmtjGon/ ...
