‘The Simpsons’ Announces New Millhouse Voice Actor Ahead of Season 36 Finale

Bart Simpsons’ best friend is changing. Well, sort of. Millhouse Van Houten, who has been Bart’s best friend since Season 1, is getting a new voice actor just in time for the finale of Season 36.

The character was voiced by Pamela Hayden for 35 years on The Simpsons, but she has since retired, so singer Kelly Macleod will step into the role. Hayden also voiced The Simpsons‘ next-door neighbor Rod (and sometimes Todd) Flanders, Chief Wigum’s wife, Sarah, Lisa Simpson’s friend, Janey Powell, and bully Jimbo Jones. Only Jones’ replacement, Parks and Rec actress Mo Collins, has been announced.

“It’s been an honor and a joy to have worked on such a funny, witty, and groundbreaking show, and to give voice to Milhouse (and Jimbo Jones, Rod Flanders, Janey, Malibu Stacy, and many others),” Hayden said in an Instagram video in November 2024. “Here’s to everyone who made this terrific ride I’ve been on possible.”

If fans want to hear Hayden’s voice, they will have to go back and watch old episodes because Macleod will voice Millhouse for the first time on the Sunday, May 18 season finale titled “Estranger Things,” according to Entertainment Weekly. The finale airs on Fox at 8/7c.

The episode description reads, “When Bart & Lisa stop watching Itchy & Scratchy together, Marge fears that they’ll start to drift apart… but she has no idea how bad things are about to get!”

The outlet reports that Macleod will only have a small part in the finale as Millhouse has one line in the episode. His voice will also sound different as he Bart, and his sister, Lisa, will all appear as adults.
