The wisecracking pals tried a matching "husband and wife" look on the red carpet -- Fey, 42, showed off her figure in a sleeveless custom cream silk and black L'Wren Scott dress embroidered in Chantilly lace, and Poehler, 41, opted for a sleek black tuxedo jacket, cropped slacks and a stunning Chopard diamond lariat necklace.
"They're terrified because it's live and didn't feel like they were ready … they were shaking in rehearsal!" a source told Us Weekly of the pair's first-time hosting jitters.
But if the two former Saturday Night Live comedians were nervous, it didn't show on the red carpet.
"[The Golden Globes] is just the right amount of weird for us," Poehler told Entertainment Weekly last week, adding that she hoped their zany zingers would "kind of encourage people to go off their meds for one night."
