O to the M to the G! Who wants to swoon? Well, if you are a Belieber and you love every note that he sings, then you are going to melt when you hear Justin Bieber sing a verse of 'Heartbreaker,' his new (and forthcoming) single, in an Instagram video.

We'll admit -- It's so swoon-worthy.

He sings, "Oh girl I got a secret place that we can go / Cuz girl I really wanna be alone / And baby nobody else gotta know..."

And then it cuts out.

What a tease.

We know Beliebers just lost their collective minds over this snippet. But what about Selena Gomez? Will she be moved? Was she moved by it when she first heard it?
