(Cover) - EN Showbiz - Justin Bieber says that just because his voice is breaking, it doesnt mean hes abnormal.

The Canadian pop sensation taught himself to play the piano, drums, guitar, and trumpet as he was growing up. In early 2007 at the age of 12, Justin sang Ne-Yo's So Sick for a local singing competition and a video of the performance on YouTube as well as videos of Justin singing covers of various R&B songs.

The 16-year-old was finally discovered in 2008, but achieved worldwide success last year when he released his single Baby in January.

Justin who is co-managed by R&B sensation Usher has revealed it annoys him when people make comment about his voice breaking because its a natural progression for any male voice.

Everybodys voice changes so its not like its abnormal. There are a lot of singers that have gone through the vocal change, like Usher, Justin Timberlake and Michael Jackson, Boyz II Men, he told Cover Media.

Justin says that the transition hasnt been a problem for him. The singer says he is aware of the fact that his voice will be forever changing.

It hasnt been an issue for me. If youve seen my movie youve seen that my voice has continued to drop and its going to get deeper and deeper, so Im not really worried, he explained.

The singer revealed early last year that his voice was breaking, leaving him unable to sing his signature hit Baby in its original key. (C) Cover Media
