Has Rebecca Black been taking singing lessons?

The viral video star, who broke YouTube records with her horrible video to the equally horrible song "Friday," just posted a new cover online ... and it's actually not bad.

The young singer shared a new video of her and friend Dave Days performing a stripped down version of Rihanna's "Stay" with Mikky Ekko.

Maybe it's the lack of auto tune or the video that isn't cluttered with literal interpretations of the lyrics ... but Black hasn't sounded better.
