Everybody is getting a piece of Michael Jackson when 'Glee' pays tribute to the late King of Pop on the Jan. 24 episode.

According to TV Guide Magazine, the cast will perform 12 songs from Jackson's extensive music catalogue, extending back to his time with the Jackson 5.

What's making New Directions so into MJ? Mr. Schuester, of course! After the former Troubletones express some regret about not being included in the Jackson family medley New Directions did at Sectionals, reliable Mr. Schue declares it Michael Jackson week.

Chris Colfer admitted to becoming quite deft at avoiding the question about what's going on with his character on 'Glee.' He even tried to do it again when Jay Leno asked him the question on 'The Tonight Show' (Weeknights, 11:35PM ET on NBC), but it didn't work out so well.

"You guys were leaving, and then no you're getting a TV spinoff, and then you're staying. So what's happening?" Leno asked.

"The truth is people forget that 'Glee' is still a TV show," Colfer said, immediately launching into a deflection from the point. He stayed on this topic for awhile. "We just have to survive Season 3 first before we can worry about it," he said, and then immediately dropped the teaser, "Little did I know that I would be in the hospital, literally the first week back filming."

Is there a little discord over in the 'Glee' camp? Last month Ryan Murphy said that several major 'Glee' cast members would be leaving the show at the end of Season 3. Their characters would graduate McKinley High and be replaced by new characters, just like in a real high school.

Makes sense, right? Well, yes and no. First, some of the actors concerned -- who are still under contract with the series -- expressed surprise at the news, with Chris Colfer saying that he'd found out via Twitter.

Then, last week Amber Riley said that the actors are all fine with the decision, and Lea Michele tweeted that "It's all part of the plan and it's all good."

Now, however, has Murphy's co-creator Brad Falchuk tossed a wrench into the works?

He told a Comic-Con audience that the characters are graduating, but they're not leaving the show: "It was never our plan or our intention to let them go. ... They are not done with the show after this season."

Oh, but he still had bad news for Sam fans: Chord Overstreet is done with the show.

Idina Menzel is heading back to 'Glee.'

According to Deadline, Menzel is in final negotiations to return to the Fox series for up to 10-12 episodes. Looks like Ryan Murphy is doing a little hedging on his "no guest stars in Season 3" edict.

"I'm really excited that Idina is joining the family again," 'Glee' co-creator Murphy said. "We missed her last year and we're happy that she is coming back."

Viewers will remember Menzel as Shelby Corcoran, Rachel Berry's biological mom and coach of rival group Vocal Adrenaline. The character was last seen adopting Puck and Quinn's baby, Beth.

Rachel, Finn, Quinn and Puck fans: Brace yourselves. It will soon be time to say farewell to the original McKinley High kids as 'Glee' boss Ryan Murphy confirmed that the characters who were juniors last season will graduate in May 2012.

Speaking on Ryan Seacrest's radio show on Friday, Murphy said that the upcoming Season 3 will be senior year for the original cast.

"I don't think of it in terms of eliminating or replacing. Because I think the thing about this cast is people love them and they are incredibly talented. They've left sort of an indelible mark," he said.

"The thing that I wanted to do and the cast wanted to do, we didn't want to have a show where they were in high school for eight years. We really wanted it to be true to that experience. We thought it would be really cool if we were true to the timeline."
