[marianne hansen]

who is he and why is he famous for one reason only

[Lost in the Echo]

He's the lead singer of the band Nickelback.

[mermaidfairy]

Yep, lead singer of Nickelback, and since that band's well known, so is he. :)

[Desuetude]

He's also married to the famous Avril Lavigne if that helps.

Most people hate Nickelback though for some unknown reason so he's pretty hated as well.
