There's a lot happening in episode five of "Glee," titled "The End of Twerk." As you probably guessed the episode will be tackling Miley Cyrus and the New Directioners will be learning how to do the booty-shaking dance.

That should be interesting. Also there's a rumor going around that one of the show's favorite couples could be splitting. Could it be the newly engaged Blaine and Kurt, Artie and Kitty, Marley and Jake or the new couple Dani and Santana?

According to the show's official description of episode five, Jarley might be calling it quits.

"The glee club learns the dance of the hour: twerking. Meanwhile, Marley discovers Jake's relationship with Bree and Rachel tries to convince Kurt they both should get tattoos."

Uh-oh. Is Bree aka "the new Santana" already causing trouble? It was also revealed that Marley will take on Cyrus' ballad "Wrecking Ball" also hinting that her relationship with Jake could be on the rocks.

Meanwhile, back in New York City Rachel is trying to convince Kurt to go to a tattoo parlor with her. In some of the official photo stills from the episode a terrified Kurt is seen at a tattoo shop but of course we won't know if he goes through with it until the episode airs.

Back in October rumors began circulating that Rachel was going to get a tattoo in honor of Finn Hudson. In real life, Lea Michele (who plays Rachel on the show) is a fan of tattoos. The actress was actually spotted on Oct. 21 at the Elle Women in Hollywood Awards sporting some new ink on her ribcage.

Through the cutout in her dress the words "If you say so" were visible. During an interview with Elle, Michele didn't discuss the tattoo but said that the last words her boyfriend and "Glee" costar Cory Monteith (who played Finn) said to her was "If you say so."

Other songs rumored from the episode include Beyoncé's "If I Were a Boy" performed by Unique, "You Are Woman, I Am Man" from Funny Girl performed by Rachel and Paolo, Robin Thicke's "Blurred Lines" performed by Artie, Bree, Kitty, Jake and Schue and The Royal Concept's "On Our Way" performed by New Directions.
