Justin Bieber and Carly Rae Jepsen

Canadian heartthrob Justin Bieber has been compared to Michael Jackson for his soulful singing and to Elvis Presley for his boyish good looks and moves. Bieber not only does vocals, but also plays the keyboards, piano, drums, guitar and even the trumpet. His first studio album, released in two parts in 2009 and 2010 as My World and My World 2.0, featured the hit singles "One Time" and "Baby." Both parts went on to become #1 on the U.S. Billboard chart and were certified platinum. His new album is "Believe" and already contains the hit single “Boyfriend."
