Brought together by Simon Cowell, Little Mix—winners of the UK The Ex Factor—are a reality show success story and British girl group made up of Jade Thirwall, Perrie Edwards, Leigh-Anne Pinnock, and Jessy Nelson. Successful girl groups are rare these days, but Little Mix’s first album DNA hit the top 5 in eight different countries back in 2012. Today, they’ve sold over 5 million singles worldwide and have been releasing behind-the-scenes peeks at new videos via Snapchat. In 2015, the group urged fans to join Periscope, where they live-broadcast Q&As and impromptu performances. They prove they’re actually good friends on their shared @LittleMix Twitter handle.
