There will be not be a Justin Bieber Glee episode, reports EW. Ryan Murphy, creator of Glee, said: 'Those [tributes] are reserved for artists with big catalogs. Bieber comes up in episode 13 as a small plot point. Sam sings a Justin Bieber song to win Quinn's approval.
The episode, called 'Comeback', will air later this winter and also feature Rachel and Mercedes diva-ing it out on a tune from Rent.'
