She first appeared on British television in 1991 with Channel 4 series Remote Control and then with !Viva Cabaret! in 1993, alongside similar character-based acts such as Lily Savage and Bob Downe. She has since appeared on shows such as the Jack Dee Show and Lily Live!, as well as her own series Gayle's World in 1996.
Most of her recent appearances have been as characters other than Gayle Tuesday, notably on Harry Hill's TV Burp on which she is a writer as well as an occasional performer. Gilhooly is married and has two daughters.
Gilhooly returned to television as Gayle Tuesday in 2010 with the Living series Gayle Tuesday: The Comeback.
