The Jonas Brothers are a pop-rock band consisting of three siblings, Kevin (born Nov 5, 1987), Joe (born Aug 15, 1989), and Nick Jonas (born Sep 16, 1992), originally hailing from Wyckoff, New Jersey. They released their first single "Please Be Mine" in 2005, with their debut album "About Time" dropping in 2006. Before disbanding in 2013, the trio released four more albums and starred in the Disney Channel Original Films "Camp Rock" (2008) and "Camp Rock 2" (2010) and Series “Jonas” (2009-2010) and “Jonas Brothers: Living the Dream” (2008, 2010). In 2019, the Jonas Brothers reunited, releasing “Sucker,” their first single in nearly six years. Their return to music is featured in the documentary "Jonas Brothers: Chasing Happiness” (2019).
