Judas Priest’s Rob Halford Appearing on Star-Studded Episode of ‘The Simpsons’

Countless celebrities have made cameo appearances on "The Simpsons"' over the past 25 seasons. Add Judas Priest frontman Rob Halford to the list.

Halford is making his "The Simpsons" guest spot during a guest-heavy episode scheduled to air at 8 p.m. EST Sunday, Jan. 5.

Titled "Steal This Episode," it finds Homer Simpson voicing his displeasure with movie theaters by illegally downloading films and setting up a neighborhood screen in his back yard. "Even though Homer is stealing, he’s doing it for the community, he’s doing it out of the goodness of his heart," explained the show's executive producer, Matt Selman.

Homer's new hobby puts him at odds with an FBI agent (voiced by Will Arnett) and sets in motion a chain of events that includes Halford singing the Judas Priest classic "Breaking the Law." Other celebrities lending their voices to the episode include Judd Apatow (who also contributed the script for one of this season's shows), Leslie Mann, Channing Tatum and returning "Simpsons" guests Paul Rudd and Seth Rogen.

Halford's "Simpsons" cameo serves as part of a fun-sounding start to 2014 for Judas Priest. Shortly after the episode airs, he and a few of his bandmates are scheduled to take part in the rock 'n' roll fantasy camp "Hell Bent for Vegas."

Halford and Judas Priest have been all over the place in the last couple years.

The band appeared on Fox's "American Idol" in 2011, performing with contestant James Durbin as he belted out "Living After Midnight" and "Breaking the Law."

Halford also appeared as a guest on Five Finger Death Punch's song "Lift Me Up," off its album "The Wrong Side of Heaven and the Righteous Side of Hell, Volume 1."

Judas Priest plans to release its new studio album in 2014.
