Say WHAT?!

Justin Bieber sat down with the folks at Power 106 in Los Angeles on Tuesday, and the 19-year-old pop star said that after the release of his new album Complete My Journals, he's going to retire!

Justin wore sunglasses inside for the interview, and the radio station tweeted, "poor @justinbieber got 3 hours of sleep," adding that the rest of the chat will be out today. They did however tweet some choice quotes from the Biebs, and seeing as he said he wants to "grow as an artist" and wants his "music to mature," we think he's joking about quitting the music biz.

Bieber, who later shot his music video for "Confident," added, "There is a motto that I live by -- never say never -- everyone can live their dream!" So what about the negative press? "I'm 19 I'm gonna make mistakes it's inevitable," he said. "People think I'm arrogant, I'm not, I've always been a caring and giving person."

Justin arrived at the studio with a whole bunch of smoke coming out of his van, so who knows what was really going on, but we just can't believe that he'd end his career before he turns 20! If so, there's going to be millions of very sad tweens all around the world...
