Justin Bieber is still only 19, and he reportedly admitted to Selena Gomez that he still has a lot of growing up to do.

However, he's trying. At least, that's what a source close to Selena, 20, told HollywoodLife. “Justin loves her music. He is working hard to be a gentleman and he knows her music is important to her, so he’s really being nice to her about that." The source said JB complimented Selena's new music video for "Come & Get It." Every girl loves flattery! "Justin can’t wait to see her again and is always talking to her about things he wants to do when he’s back to the US, and she’s hoping he can keep his promises."

He's still on his Believe tour, but Jelena still reportedly talk on the phone all the time. Guess we'll have to see how things go when they are back in the same area for an extended period of time. Good luck to them, or do you think they are better off apart — for a while or even permanently?

Update: This maturity thing is already hitting a rocky patch. Justin shared a new photo on Instagram, writing "Beers in the jungle."
