'Glee' to Cover Rebecca Black's 'Friday'The cast of 'Glee' will be having "fun, fun, fun, fun" pretty soon. Confused? Well, it was bound to happen. The cast of 'Glee' will reportedly cover Rebecca Black's YouTube sensation 'Friday.'

According to Vulture, the song will get the 'Glee' treatment from cast members Kevin McHale, Chord Overstreet and Mark Salling.

This isn't the first time 'Glee' has covered an uber-popular song. They have previously performed Cee Lo Green's 'Forget You,' a number of Lady Gaga's hits and later this season repeat guest star Gwyneth Paltrow will sing Adele's 'Turning Tables.'

The one difference? Those songs are by actual recording artists; 'Friday' is by a 13-year-old girl.
