Amber Riley Covers ‘All I Want For Christmas’ On Glee

Amber Riley who plays Mercedes Jones on Glee covered Mariah Carey's super hit ''All I Want For Christmas' for an all Glee Christmas special!

We have to admit, we love Amber's version! We love it so much, we think it might be better than Justin Bieber's and Mariah Carey's duet version!

Tell us what you think after hearing it!
