Rocker Marilyn Manson has made a shocking transformation for his cameo on hit U.S. show Eastbound & DOWN by ditching his trademark make-up.

The star unmasked his true identity on Tv for the first time by appearing without his usual heavy white foundation and dark lipstick to shoot a short scene for the comedy series this week (begs07Oct13).

The Disposable Teens hitmaker has reportedly been lobbying producers to cast him in the show, according to editors at Tmz.com.
