2018 and 2019
In 2018, speculation of a reunion began when the Jonas Brothers' official Instagram account was reactivated. Then, in late February 2019, the Jonas Brothers announced their comeback on social media, and just a day later, they released a new single, "Sucker," under Republic Records. Their second new single, "Cool," was released in April, followed by their new studio album, Happiness Begins, in June. Just three days before the album's release, a documentary titled Chasing Happiness premiered on Amazon Prime Video, featuring deeply personal interviews and never-before-seen footage tracking the three brothers over the course of their 14-year career.
