Johnny Depp's biography includes being a three-time Oscar nominee, a devoted father, and an object of lust for countless women.

But now he may have to add one more bullet-point -- rock star -- after playing with Marilyn Manson at Wednesday night's Golden Gods Awards concert at Club Nokia in Los Angeles.

As Manson launched into his own version of the Eurythmics' classic 'Sweet Dreams (Are Made of This),' Depp, dressed all in black with a hat tipped low over his face, hovered in the background while playing an electric guitar. In fact, most of the concert attendees didn't even know he was there until Manson shouted into the mic, "If you don't recognize my personal friend ... my personal savior, my personal guitar hero ... Johnny Depp!"

The crowd roared its approval as Depp stayed on stage to jam through Manson's song 'The Beautiful People,' remaining mostly straight-faced but occasionally breaking into a telltale smile that showed how much fun he was having.

It isn't Depp's first foray into music -- he played in a band before his acting career took off. In addition, he joined his friend Alice Cooper on stage for a club concert in London last summer, and even tweaked at Cooper in the trailer for his upcoming film 'Dark Shadows,' calling Alice the “ugliest woman I’ve ever seen.”
