Justin Bieber may have just turned 18, but in a new interview with Radio Disney, he proves that he's wise beyond his brand-new "legally adult" status when it comes to knowing the key to a successful relationship.
"It's just about being honest with one another," he tells host Jake of Celebrity Take with Jake about how he and his equally-as-famous love, Selena Gomez, maintain their relationship in the midst of Hollywood's stressors.
"You just have to be honest, that's the first thing, because if you're not honest, then the relationship is just not a good relationship. At the end of the day, your girl would appreciate you being honest more than lying to her and vice versa.
In her March interview with Cosmopolitan, Gomez, 19, showed that she and her beau's expectations line up with each other's. "If you're in love, you're in love to the fullest, and you just want to go to the movies, hang out, and be as normal as possible. I'm fortunate that I've found someone who has that philosophy."
Bieber and Gomez began dating in 2010 and have since been spotted packing on the PDA across the globe. In October, the Canadian crooner surprised the former Disney starlet by renting out an entire movie theater so the pair could watch Real Steel in private.
In "Boyfriend," Bieber debuts a more mature side of his musical career. The chorus of the first song off his forthcoming album, Believe, has the lyrics: "If I was your boyfriend, never let you go / Keep you on my arm girl, you'd never be alone / I can be a gentleman, anything you want / If I was your boyfriend, I'd never let you go / I'd never let you go"
