Justin Bieber, Selena Gomez 2013 [VIDEO]: 'Heartbreaker' Singer Close to Winning 'Stars Dance Songstress Ex-Girlfriend Back?

Justin Bieber is apparently not over Selena Gomez. The release of his latest song, "Heartbreaker," made this pretty apparent, but now a new source close to the Biebs is saying that he is pulling out all the stops to try and win his ex-girlfriend back! What do you think of this rumor?

"Justin is going hard to get her back," the insider explained. "They weren't talking but he wore her down again and she's taking his calls again. She wants to keep it strictly friends, but it's a slippery slope on that because they have such intense chemistry, she's just built up walls to protect herself."

Other reports claimed that the two hardly talk, but perhaps that's because of the "slippery slope" mentioned above?

The source continued: "Justin has major game, he's good at saying all the right things. And he's looking hot! I'd say there's a good chance they'll go for another round. Of course, all her friends are hoping she'll stay strong and keep him in the friend zone."

Whoa! Do you think Justin Bieber would ever settle for the "friend zone"? Nobody likes being there, so why would the biggest pop star in the world even consider it? Perhaps Bieber will accept the "friend zone" terms in order to play the long game and eventually woo Selena? What do you think?

Maybe he has already started the wooing. Check out a recent Instagram video post from Justin:

Here is what he "sang": "You say that you don't wanna talk but it's cool, been thinkin' about you all day long, hopin you'll pick up your phone. And I know that I don't wanna lose your love."

Do you think he's lip-syncing his own song to Selena?
