Two of our favorite Glee characters are teaming up onstage for the Season 5 finale! Brittany (Heather Morris) will be back, and she's going to be helping Mercedes (Amber Riley) during a pivotal live performance.

In Season 5, Episode 20: "The Untitled Rachel Berry Project," Mercedes will perform an original song called "Shakin' My Head" at an event to promote her burgeoning music career. And to help Mercedes out, Brittany will hop up onstage with her to become one of her backup dancers!

We've already gotten to watch this scene, and it's truly amazing, between Mercedes's incredible voice and Brittany's killer dance moves. And the song itself is quite funny, with lines like, "Why does gravy give you heart attacks?" We agree, Mercedes: Life is just unfair sometimes.

Among the people who are enjoying Mercedes's performance is a new character played by Glee guest star Kristen Schaal. And at the end of the tune, Sam (Chord Overstreet) runs up onto the stage to give Mercedes a hug. So sweet! 

We haven't seen Brit and Mercedes hang out much in the past, but we're loving their new friendship. A note to Ryan Murphy: More of these two, please!

Are you looking forward to seeing Mercedes and Brittany perform together?
