The preview for the next episode of 'Glee' has surfaced and gives fans a sneak peek at the much-talked about Justin Bieber cover. 

Entitled 'Comeback', this episode features a solo performance from the Glee club's newcomer, Sam Evans (played by Chord Overstreet), as he decides to channel his inner Bieber with a rendition of the teen superstar's hit single 'Baby'. 

This will be the first time the show has attempted one of the young singer's tracks after Ryan Murphy recently explained:

"Glee is NOT doing a Justin Bieber tribute episode. We are not doing any more of those this season. Those are reserved for artists with a big catalogue, ala Madonna and Britney, etc."
