Stephanie Ann D'Abruzzo (/dəˈbruːzoʊ/;[1] born December 7, 1971) is an American voice actress, puppeteer and singer.

D'Abruzzo is also well known for playing Kate Monster and Lucy the Slut in the original Broadway production of Avenue Q in 2003.

[5][6] At the university's Communications Residential College (CRC), she could often be caught watching (and, as it turns out, studying) Sesame Street.

[citation needed] Eventually, D'Abruzzo began to consider puppetry as a career, in part as a solution to finding acting roles after she "gained more than the Freshman 15 and [got] a bad perm.

"[7][4] D'Abruzzo's production of a puppet television show called Freeform won the National College Emmy award for comedy.

[6] D'Abruzzo has spent much of her career performing as a puppeteer in children's television, but she is known for originating the roles of single schoolteacher Kate Monster and sultry chanteuse Lucy the Slut in 2003 in the Broadway musical Avenue Q.
