Justin Bieber is a straight-up Casanova on the cover of Seventeen Magazine.

Between filming two teasers (and one fake out) for his forthcoming single "Boyfriend," Justin Bieber found the time to pop by Seventeen Magazine to shoot his cover shot for the publication's May issue.

Inside Seventeen, Justin discusses everything from his fans to his new sound to his relationship with Selena Gomez, explaining "I'm just trying to make her happy, that’s all. I think it’s important to make all women feel like they’re princesses, because every girl is a princess. I’m serious." Um, WE DIE!

Clearly, someone's mama taught them right. Props to you, JB. And also, if all women are princesses, then that means I'm a princess. So you should send me gifts! See? Logic!
