While nothing is official yet, Lea Michele from “Glee” talked about Justin Bieber and the possibility of him making an appearance on the show:
I don’t know about Justin Bieber coming on the show, but he would be awesome. But I will tell you this—breaking news from Lea Michele!—we have an Academy Award winner coming on Glee in the next few episodes that is not Justin Bieber.
Do you have your fingers crossed that Justin will be on “Glee”?
*fingers crossed*
i think it will help the show like it helped CSI a lil but he wuz only in the middle and he wuz on the end end of the episode hopefully he would b more on the next episode right 
luv u Justin
