You may have never heard of Karmin, I didn't until I found this video of them covering Chris Brown's 'Look at Me Now.' Karmin is a male/female duet comprised of Amy and Amy Heidemann and Nick Noonan that performs cover songs trying to keep them simple. In their latest cover song Amy does her best Lil' Wayne impersonation, but really kills Bustas part about halfway through the song. Check out the video after the jump.

What do you think? Pretty impressive in my opinion!

Check out their Facebook or follow them on Twitter!
