Challenge extended, Darren Criss.

A few hours after Fox released the full performance of this Glee cast member leading a rendition of Michael Jackson's "Wanna Be Startin Something," the network has also given us a glimpse at Naya Rivera and Grant Gustin - as Santana and Sebastian, respectively - going head to head on the King of Pop's "Smooth Criminal."

And it's pretty awesome.

Accompanied by nothing but a couple cellos, watch these characters circle each other below, as…

I liked Glee's Michael Jackson tribute episode a lot more than I thought I would. A backward compliment? Sure. But, hey, it's still a compliment.

Unlike past tribute episodes - to Britney Spears, to Christmas - this one managed to weave in a few key developments, mostly basing its MJ covers around ongoing storylines and legitimate character realizations...

... with the exception of Artie's totally random moment of anger, which resulted in an imagined "Scream" performance and an imagined…

In April, members of New Directions will be come down with a case of Saturday Night Fever.

Indeed, they'll be Stayin Alive, Stayin Alive, as Glee creator Ryan Murphy has confirmed to TV Guide Magazine that an episode in honor of The Bee Gees is on tap for this spring.

Glee Winter Premiere Promo

"We've never done disco on the show," Murphy tells William Keck, adding that his fantasy is to recruit John Travolta for a cameo because the Saturday…

Scream it out loud, Gleeks: this Fox hit will be Startin' Somethin' on January 31, as Glee is getting ready to rock with Michael Jackson.

Fresh off an episode that crammed many storylines into a single hour, the upcoming installment appears to have a far narrower focus, as viewers will be moonwalking along to covers of iconic singles originated by The King of Pop.

They also might find out Rachel's answer for Finn.

We've posted a number of photos…

New year. New Glee! Following a Christmas episode for which I could not hide my disdain, that was the attitude I adopted heading into the winter premiere, "Yes/No."

It lasted about .07 seconds, I'm sorry to say.

Within the first five minutes, this was the random sequences of events thrown our way: an immediate cover of "Summer Nights" from Grease; the announcement that Beiste and Cooter eloped; a Becky-based narration by Helen Mirren because people with Down's Syndrome…

We can, and undoubtedly will, continue to argue about my take on this week's Glee episode, but hopefully we can all get excited together over the following show scoop:

Glee has cast Rachel's two dads!

The roles that have been discussed almost since we met young Ms. Berry will go to Jeff Goldblum and Brian Stokes Mitchell, Michael Ausiello reports, and both will debut on the February 14 Valentine's Day-inspired episode of the series.

Goldblum is a veteran of the…

Fox President Kevin Reilly confirmed yesterday that Glee will not be spun off in any way - but that doesn't mean season four won't look very different from anything we've seen previously on the show.

Look for Rachel, Kurt and the senior class to graduate, while likely still being involved in some capacity. New characters, meanwhile, will step up, with E! News reporting Grant Gustin may very well be promoted to series regular status in time for the fall.

Gustin…

Grant Gustin may or may not be promoted on season four of Glee.

But he'll definitely be doing some damage on the show's upcoming Michael Jackson tribute episode.

The actor spoke to E! News last night and said his villainous Warbler will "inflict pain on somebody" early on in the installment, leading to Santanta confronting Sebastian at Dalton Academy - and the two breaking into a rendition of "Smooth Criminal."

Gustin will actually be involved in two numbers beyond…

Warning: this could get ugly.

Two TV Fanatic staff members - Matt Richenthal and Chris O'Hara - have opposing takes on this week's Glee Christmas episode. The former thought it was essentially an hour-long promotion for the show's latest CD, lacking plot, logic and direction. The latter... thought otherwise.

Read through both sides in the following edition of the Glee Round Table and then sound off with your opinion.

Matt: There…

We are not here to once again debate the merits of this year's Glee Christmas episode. You may do that by jumping in to our most recent Round Table discussion.

Instead, we're here to post a performance that was deleted from the installment, as Naya Rivera got her sexy Santa on for a rendition of a holiday classic that was cut from the final, edited broadcast.

Watch now as Santana and Finn frequent a jewelry store and the…
