‘Glee’ Season 4 Promo: Kate Hudson Gets Sassy, Plus Guess Who’s at McKinley (VIDEO)

'Glee': Six S4 Spoilers!
Find out some fresh deets from the FOX musical.
Gleeks, the countdown to the first day of school at McKinley High has officially begun. Production is already underway for the fourth season of the Fox hit, and Glee co-creator Ryan Murphy just couldn’t wait share some new footage with the fans.

In this new FOX promo, we get a glimpse of guest star Kate Hudson in action. Playing Rachel’s (Lea Michele) jaded dance instructor, the actress has certainly brought her signature sass to Glee. Back at McKinley, the choir room is looking a little empty after the seniors graduated at the end of last season.

Now Mr. Schue (Matthew Morrison) needs to rebuild New Directions, and it looks like there’s a recent transfer who’s up for the challenge.

Find out who after the jump.

“The Glee Project” Season 1 runner-up Alex Newell is reprising his guest starring role as Wade Adams, the standout member of  Vocal Adrenaline. During Season 3, Wade revealed to Kurt (Chris Colfer) and Mercedes (Amber Riley) that he identified as a fierce diva named Unique.

We also get a first look at Sue’s (Jane Lynch) baby. Although, there’s no celebrity baby daddy in sight. Meanwhile, the first song of Season 4 is “It’s Time” by Imagine Dragons, as sung by Blaine (Darren Criss). Unfortunately Gleeks, Finn (Cory Monteith) is nowhere in sight.

Glee Season 4 kicks off Thurs., Sept. 13 at 9 p.m. ET on Fox.
