In her very first late-night talk show appearance, Mad Men's Jessica Pare admitted to a case of stage fright.

"I'm really excited and a little terrified," she said on Wednesday's edition of Late Night With Jimmy Fallon. But Fallon, a fan of Pare's game-changing "Zou Zou Bisou" performance from season five, quickly calmed her nerves, saying: "You're killing it on the show. We love you so much."

Pare drew laughs when she confessed to fishing for reactions on Megan Draper's rendition of the French song ("Hey guys, 'Zou Zou Bisou,' right?") and also when she told an anecdote about meeting Daniel Day-Lewis at this year's SAG Awards. He "turned around and he's like, 'Oh, what a pleasure to meet you,' to me!"
