'Glee': Graduation Countdown Begins In 'Big Brother' (VIDEO)

It's the beginning of the end of high school for some "Glee" characters as the Fox musical series marches toward the big graduation and its Season 3 finale. Who is sticking around? You'll have to tune in to find out, but in the new promo below, you can see some of the graduating seniors getting ready for their big day -- yep, there are caps and gowns.

The promo for "Big Brother" (Tues., April 10, 8 p.m. ET on Fox) also includes glimpses of new performances -- white leisure suits! Gotye's "Somebody That I Used To Know"! -- and "White Collar's" Matt Bomer as Blaine's (Darren Criss) older brother Cooper Anderson.

The final episodes of Season 3 will also include guest appearances by Whoopi Goldberg and possibly Lindsay Lohan and an entire tribute episode to the late Whitney Houston.

Check out the promo for "Big Brother" below and take a look at photos in the slideshow.

CORRECTION: A previous version of this post indicated that Quinn (Dianna Agron) was not in the promo video, but it's since been brought to our attention that you can see her at the 23 second mark. Apologies for egging on Gleeks who were hoping for Quinn's car accident to be the end of the road for the character. Errr ... We're glad she's seemingly back!
