Hayden, who voiced Bart Simpson’s nerdy sidekick Milhouse Van Houten, Jimbo Jones and others, said she is leaving the show to pursue other opportunities.

Veteran "The Simpsons" voice actor Pamela Hayden will bid farewell to Springfield's Milhouse, Jimbo Jones and all the other characters she helped bring to life for more than three decades. Fox announced Wednesday that Hayden will retire from the hit animated series after 35 years.

Hayden, 70, who voiced Milhouse, Jimbo Jones, Rod Flanders, Janey and Malibu Stacy, will sign off from “The Simpsons” on Nov. 24 in a “Treehouse of Horror” episode.
