`GnR`s Duff Mckagan Is Bieber fan

London: Former `Guns N` Roses` bassist Duff McKagan is a `bieliber` and was impressed by teen sensation Justin Bieber when he saw him perform live.

The 47-year-old bassist is full of praise for the 17-year-old teen singer and is impressed by his talent, reported Contactmusic.

"Do you know what? Justin`s a rocker. Man, he actually sings at his gigs, and the band`s a real band, and he plays drums and he`s really great. Justin Bieber is a rocker for sure," said McKagan.

The `Velvet Revolver` star who discovered the `Baby` hitmaker`s music through his two daughters, 13-year-old Grace and 10-year-old Mae Marie, is glad to watch his girls` favorite star with them.

"Grace is 13 and she finds new cool stuff and she`s into Justin Bieber. And I take them to every gig they want to go to. Justin Bieber concert, great. Jonas Brothers, Taylor Swift," added McKagan.
