The rumours that the 'Glee' cast tackled Rebecca Black's viral hit 'Friday' have been proven true as the cover has surfaced online. 

Mark Salling, Chord Overstreet and Kevin McHale (Puck, Sam and Artie) perform the track, which is set to feature in the forthcoming episode entitled 'Prom Queen' that will air on Tuesday, May 10 in the U.S. The same episode will also see Gleeks treated to renditions of Adele's 'Rolling In The Deep' and ABBA's 'Dancing Queen'.
