For many musicians, being transformed into a 'Simpsons' character is an honor outweighed only by a Nobel Prize. Many of rock and metal's most iconic figures have been turned yellow by 'Simpsons' animators, and Judas Priest singer Rob Halford is the latest to receive the cartoon treatment.

Halford will appear in an episode titled 'Steal This Episode,' which is scheduled to air in January. The episode is already a star-studded affair, with animated appearances from Judd Apatow, Will Arnett, Leslie Mann, Paul Rudd, Seth Rogen and Channing Tatum. Rob Halford's inclusion ups the star level even more, appealing to an entirely new fan base.

According to Entertainment Weekly, the plot of 'Steal This Episode' revolves around Homer Simpson's disdain for movie theaters. Bart teaches Homer how to illegally download films, which leads to backyard screenings at the Simpson's house. Rob Halford sings a parody of the Priest classic 'Breaking the Law' in an attempt to bring Homer to justice.

Judas Priest recently finished writing their 17th studio album. “It’s heavy," Halford tells Billboard. "It’s something we think our Priest fans will be thrilled with. We know we have a reputation to maintain, and we know we have to deliver something really strong and solid. The album is going to be full of all the great things you love about Judas Priest — I don’t think I can say anything more than that without being hung, drawn and quartered.”

Be sure to look out for Rob Halford's appearance on 'The Simpsons,' which will air this coming January.
