Actor Rob Lowe spoke his mind on "Oprah Prime" and discussed his feelings towards current teen pop star Justin Bieber.

"He makes really good music, he does, but I think he knows the dark secret, and the dark secret is 80 percent of his audience doesn't give a s**t about the music. And he knows it. It bums him out," contactmusic.com quoted the 1980s' teen idol.

"They care about lemming-think, and their girlfriends and who's oohing and aahing and screaming. It has nothing to do with what he's doing as an artist.

"He is the guy who is standing in front at a moment that they're going through a developmental thing. It's natural, it's all great, but if it wasn't him, it would be somebody else, like it was me," he added.
