Glee: The Power of Madonna

It's the most anticipated TV moment of the season: Glee's tribute episode to Madonna!

The whole cast dressed up in some of M's most iconic images for a TV Guide photoshoot; Oprah invited a real-life glee club to perform a cool rendition of "Vogue" (the VMAs baroque version); and Youtube's preview of "The Power of Madonna" unveils some incredible versions of M's music.

May the countdown begin!
