Next week on GLEE, Gwyneth Paltrow makes her debut appearance at McKinley High as Mr. Schuester's substitute. But while Mr. Schuester is sick, he hallucinates mini versions of his glee club students. Here's a sneak peek of the tiny GLEE cast from the "Substitute" episode of GLEE airing Tuesday, Nov. 16.

GLEE made its triumphant return to prime time with an astounding 12.3 million viewers tuning in to the Season 2 premiere. The anticipation and excitement for GLEE music reached new heights with over 250,000 new tracks downloaded in the first 48 hours available. This incredible response yielded more record breaking moments for GLEE; it's the first time all singles from any episode simultaneously appeared in the top 10 of iTunes Top Songs chart. Additionally, the GLEE cast version of Jay-Z's anthem "Empire State of Mind" has the single highest first day sales for any GLEE track released to date.

To date over 13 million GLEE songs have been digitally downloaded, with over 5 million albums sold worldwide. GLEE scored three consecutive #1 releases with GLEE: The Music, Volume 3 Showstoppers, GLEE: The Music, The Power of Madonna and GLEE: The Music, Journey To Regionals.
