Good news, Gleeks! We now know exactly what songs the remaining McKinley high schoolers will be singing in episode one of Glee, just in time for the season 4 premiere next Thursday! Warning: if you don’t want to know about any premiere spoilers, we suggest you stop reading now. Okay, last chance to click the X, cause here they come! Darren Criss and Kevin McHale will be doing a mashup (our fave!) of Justin Bieber’s “Boyfriend” and Britney Spears’ “Boys” (which you can listen to right here). Um, can you say epic? The season’s first celeb guest will be Kate Hudson, who’s going to try her hand at a Lady Gaga/ Jennifer Lopez combo. Throw in Carly Rae Jepsen’s “Call Me Maybe” and we believe that you’ve got yourself the most fab episode yet! Our friends over at Clevver clearly have tons to say about this amaze news, so be sure to check out the vid above!
