Lea Michele and Jonathan Groff's Christmas Duet Has Me Feeling Extremely Gleeful

Rachel Berry and Jesse St. James, er, Lea Michele and Jonathan Groff, are back together again! On Monday night, the best friends and former costars performed a beautiful rendition of "I'll Be Home For Christmas" on The Tonight Show Starring Jimmy Fallon, and it's giving us all the Glee feels. The duo were in perfect harmony as they sang on a festive stage, complete with twinkling lights. At one point, Groff even took Michele's hand and danced with her. Aww! If their sweet vocals don't make you feel all warm and fuzzy inside, their adorable friendship will.

Michele and Groff certainly have a lot of experience singing together. The two first met playing love interests in the 2006 musical Spring Awakening and went on to share the screen in Michele's hit show Glee (their characters even end up together in the finale). We think it's about time these besties hit the road together for a tour! Watch their lovely performance above.
