I'm sure you've heard of this couple already. They've been making covers for a while now but it just dawned on me to post a video of them on here! Basically, they're a couple who sing covers (and a few originals) and upload them to YouTube. <-- go check their page.
This video is their cover of Chris Brown's Look At Me Now. Um, and yes she raps Busta's part. Just check it out for yourself!
