Ana Gasteyer plays Katherine on the new NBC comedy "American Auto."

During her six years on "Saturday Night Live," Gasteyer created several iconic characters, including middle school music teacher Bobbie Moughan-Culp, NPR radio host Margaret Jo and Lilith Fair poetess Cinder Calhoun, as well as spot-on impressions of Martha Stewart, Celine Dion and Hillary Clinton. 

This holiday season, Comedy Central will premiere "A Clüsterfünke Christmas," which Gasteyer and fellow "SNL" alum Rachel Dratch wrote, executive produced and star in. The special is a parody of the corny and ubiquitous traditional holiday TV movie. Previous TV credits include "The Goldbergs," "Lady Dynamite, "People of Earth," "Suburgatory" and "Curb Your Enthusiasm." 

On stage, Gasteyer has starred on Broadway in "Wicked," "The Rocky Horror Picture Show," "The Royal Family" and "Three Penny Opera." Other stage credits include "Funny Girl" and "Passion" at the Chicago Shakespeare Theater, which earned her a Jefferson Award nomination. At the Hollywood Bowl, she played Miss Hannigan in the musical "Annie."

Gasteyer is also a highly accomplished singer and songwriter. This winter, she'll embark on a Christmas tour in support of "Sugar and Booze," her recent album of seasonal favorites and holiday originals.    

Gasteyer attended Northwestern University and honed her comedy skills at The Groundlings in Los Angeles. She resides on the East Coast with her husband, children and rescue pup, Gloria.
