Bayer burst onto the scene during her debut season with her impersonation of Miley Cyrus in the wildly popular sketch "The Miley Cyrus Show." She has continued to wow audiences with her impressions of Hillary Clinton, Kourtney Kardashian and "Fox & Friends" host Gretchen Carlson, as well as her recurring characters Jacob the Bar Mitzvah Boy and the ditzy porn star-turned-aspiring-pitchwoman Becky.
Bayer came to the cast of "SNL" from iO Chicago, the Annoyance and the Second City, having trained in the Chicago area and performed as an understudy for the Second City's Mainstage and touring company. She starred in the acerbic puppet show "Felt" and the improv team "Revolver" at iO Chicago, wrote and performed in the Annoyance Theatre's "Swear Jar" and performed stand-up at Zanies.
Originally from Cleveland, Bayer received her degree from the University of Pennsylvania in 2004. While in college, she interned at "Sesame Street" and "Late Night with Conan O'Brien" and was a member of Bloomers, a storied all-female comedy troupe.
Bayer lent her voice to Universal Pictures' animated feature "Despicable Me 2" and stars in the web series "Sound Advice with Janessa Slater" that she co-created with her brother Jonah for Broadway Video's Above Average. She can also be seen in Judd Apatow's upcoming comedy "Trainwreck."
Bayer currently resides in New York City. Her birthday is November 14.
