(CBS News) Justin Bieber is no longer singing about his "Baby." Now, the 18-year-old heartthrob wants to be your "Boyfriend."

In his new single, "Boyfriend," released today, Bieber sings: "If I was your boyfriend, I'd never let you go, I can take you places you've never been before."

Co-written and co-produced by "Cooler Than Me" singer Mike Posner, the track will appear on Bieber's upcoming album, "Believe," due out later this year.

"I'm maturing, and my music's maturing, so I wanted to do something different," the Canadian singer told USA Today about the new song. "I've got a lot of great collaborators working with me, and we're thinking outside the box."

The song, with its R&B vibe and sing-songy rap, is already getting comparisons to Justin Timberlake's solo work.
