Is Justin Bieber Boyfriend Single for Selena Gomez?

Justin Bieber is growing up fast. It seems like just yesterday that Usher introduced us to this cute little kid from Canada. Then he became an international sensation, started dating Selena Gomez, and is now back to dominate the charts. Take a listen to his new single, "Boyfriend," and you'll see what we mean -- it's definitely a long way from the sugary sweet pop of his 2010 hit "Baby."

The Biebs channels another Justin in "Boyfriend," Justin Timberlake. It has a very Justified vibe, so we're tempted to call it retro since that was a decade ago. But better than that, it has a much more interesting and mature sound than tracks off the My World and My World 2.0 albums. With mega artists Kanye West and Drake also appearing on the album, we think Believe might actually make a fan out of those who have been avoiding Bieber like the plague.

We can't help but wonder how much inspiration Justin has gotten from his relationship with Selena Gomez. "Boyfriend" is clearly about a guy who's ready to take care of the girl he loves, repeating "If I was your boyfriend, I'd never let you go." People everywhere seem amazed that they're still together more than a year after relationship rumors started spreading. Though they were coy at first, they seem to be getting more comfortable in the spotlight so it wouldn't be a surprise if they had each other in mind when writing songs in the studio.
