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.

New York (AP) — Pamela Hayden, the longtime voice actor behind Milhouse Van Houten — Bart Simpson’s very uncool friend — is stepping away after 35 years of whining. 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.
