GLEE Previews This Week's New 'I Do' Episode

FOX's mega-hit musical comedy series Glee just released a new video teaser centered upon this week's wedding-themed episode, "I Do"!

Check out the promo below.

"I Do" depicts the years-in-the-making nuptials of Will Schuester (Matt Morrison) and Emma Pillsbury (Jayma Mays). Among the musical numbers expected to be performed in this special episode is the caustic "Getting Married Today" from Stephen Sondheim & George Furth's COMPANY, as well as Ellie Goulding's current hit "Anything Can Happen", Depeche Mode's "Just Can't Get Enough" and two classic throwback duets - "You're All I Need To Get By", made famous by Marvin Gaye and Tammi Terrell, in addition to "We've Got Tonite" by Kenny Rogers and Sheena Easton.

Glee is now in its fourth season and is expected to be renewed for season five (and potentially more) in the coming weeks. It is regularly FOX's highest-rated scripted show.

GLEE was created by Ryan Murphy, Brad Falchuk and Ian Brennan.
