Fifth Harmony announced on Twitter Monday that they're going their separate ways. The girl group, famous for their hit single, "Work From Home," will be working on their solo careers. The Miami-based group says the break will allow them to "gain new experiences, strengths and perspectives that we can bring back to our Fifth Harmony family." The group formed on 'The X Factor' in 2012. One original member, Camila Cabello, left in 2016, making them a quartet.
