Rebecca Black Covers 'Chained To The Rhythm'

You might remember Rebecca Black from her viral song Friday. 

Well she is all grown up and actually has some really good pipes! She recently covered Katy Perry's new song 'Chained To The Rhythm!'

Rebecca and Katy actually go way back... to when Black was featured in the video for the song TGIF! 

Too bad she will always be remembered as the girl who sang Friday.
