Blake Shelton - Blake Shelton Compares Justin Bieber Fever To Power Of Presley

The Baby hitmaker was greeted by screaming fans in the audience as he premiered a clip from his new Boyfriend video on the show, and Shelton, who serves a judge on the programme, has been left stunned by the 18 year old's rapid rise to fame.

He tells Hollywood Life, "You would have to be living under a damn rock not to know who the kid is and the impact that he is having. I never witnessed anything like that, it's got to be similar to what happened with Elvis when he would come walking into a room. People screaming and crying, I literally looked at a group of girls that were in the audience and they were crying!

"Man, I like that kid. He came over and shook all of our hands, so he seems to be a really good kid on top of everything else, on top of being extremely hot and talented!"
