Harry and Gemma Styles
One Direction's hairstylist Lou Teasdale just released her new DIY style book The Craft in the UK and had a party last night to celebrate. Of course, her A-list friends like Harry Styles, Liam Payne, and Ed Sheeran all attended. We're sure Niall Horan would have too if he hadn't been busy meeting the Queen of England.
