"Glee" Season 5 spoilers increase in online servings as the FOX show's winter premiere on Feb. 25 is fast approaching. There will be more New York, less Demi Lovato, and the Nationals could change the show forever. Meanwhile, Dianna Agron and Lea Michele disprove any rumoured feud between them in cute Twitter photos.

Spoiler alert: This feature contains spoilers on Glee Season 5 in 2014. Read at your own risk. The show returns in three weeks' time. Episode 9, "Frenemies," airs on Feb. 25.

Glee creator Ryan Murphy has been hyping up the show's original cast's appearance in the 100th episode. But the show went on hiatus, so it's been a long wait for Glee Season 5, Episode 9.

Glee Season 5, Episode 9, titled "Frenemies," will pit Lea Michele's Rachel Berry and Naya Rivera's Santana Lopez against each other.

Jayma Mays is leaving Glee, and the Emma Pillsbury ending will be seen from Glee Season 5, Episode 10, which is called, "Trio." (Is the character dying, or will there be a divorce?)

The trio in Glee Season 5, Episode 10 are stars Adam Lambert, Demi Lovato, and Chris Colfer. This could be Demi's last episode in Glee. The young celeb has previously quit the X-Factor, saying she wants to focus on her music.

Come March 2014, things will be changing fast in Glee Season 5. The showrunners will focus more on New York. The show's special 100th episode is coming, but first there's the Nationals for the New Directions.

Glee executive producer Brad Falchuk has recently teased some F.R.I.E.N.D.S. (NBC) tribute coming up in Glee Season 5. See the interesting Twitter photo here. (Lea Michele's Rachel Berry as Rachel Karen Greene, then?) Artie (Kevin McHale), Blaine (Darren Criss), Sam (Chord Overstreet), Kurt (Chris Colfer), Santana (Naya Rivera), and Tina (Jenna Ushkowitz) are also in the image obviously inspired by the show's "I'll Be There for You" opening credits video.

Meanwhile, Lea Michele and Dianna Agron appear to be getting along just fine in their recently posted Twitter photos. The two were reported to be at odds when Agron did not make an appearance in "The Quarterback," the Cory Monteith tribute earlier in Glee Season 5.

"So thankful for my amazing glee family. I love them so much," Lea Michele tweets on Jan. 30. The post comes with this photo, showing Lea and Dianna sitting next to each other.

For her part, Dianna retweeted another tweet by Lea, which shows a photo of just the two of them together. "Want to dress like this every day," Dianna captions this 80s glam photo.

To sum up, there will be a little bit of 90s sitcom with a tribute to Friends in Glee Season 5. There will also be some 80s glam, presumably in the show's 100th episode, which is also a reunion special.

On top of all these, Gleek fans can hardly wait to see a Brittana (Brittany and Santana) reunion. Spoilers confirm Heather Morris reprises her role as Brittany S. Pierce in the 100th episode airing in Glee Season 5.
