Canadian teenager Justin Bieber became a pop chart sensation in late 2009, after building a solid fan base on YouTube with videos of himself singing covers of popular R&B songs. He went on to be the teen heartthrob of 2010, famed for his curved-around-the-forehead hairstyle and his throngs of screaming teenaged fans. Justin Bieber's career began with performances at a talent show in his hometown of Stratford, Ontario. He posted videos his mom had taken in 2007, and over the next two years added to his archive while earning the love of internet fans. A record producer from Atlanta, Georgia noticed his videos, and in October of 2008 Bieber signed with Island Records and began working on his first album. My World was released in November of 2009, and by then Bieber already had four singles on the charts, thanks to well-orchestrated advance releases. Mentored by pop star Usher, Bieber released an updated version of the album in 2010 (My World 2.0) and toured the world. His best-known songs include "One Less Lonely Girl," "First Dance" (with Usher), "One Time," and "Baby" (featuring rapper Ludacris).
