Anne Hathaway has been confirmed as an upcoming Glee guest star.

While this is exciting news, many fans are more interested in future Glee music numbers than actor/actress appearances. What singles and/or artists are on tap for the show, once it returns next month from hiatus?

We can offer the following scoop:

• The show will feature two Paul McCartney songs in February, one ("Silly Love Songs") sung by Blaine.
• On what Amber Riley describes as a "diva-off" with Rachel, she'll sing "Take Me or Leave Me" from Rent.
• Coach Beiste will sing a country song on the February 22 episode.
• The series will cover two Justin Bieber songs, most likely "Baby" and "Somebody to Love."

Which of these teases has you most excited?
