Last month, Olivia and her fiance Jason Sudeikis both performed at New York’s Upright Citizen’s Brigade Theater in a show called Gravid Water.

“Olivia and Jason did a scene together…Olivia memorized the lines to a scene, while Jason improvised the other character’s lines. They were hilarious!” a witness told JustJared.com.

FYI: Olivia is wearing a Talbot Runhof dress, Nicholas Kirkwood heels, Iwona Ludyga Design jewelry, and Ariel Gordon black rose cut studs.
