On Friday, for the first time in his mascara-covered career, usually outspoken Marilyn Manson was rendered speechless.

And for good reason.

The rock 'n' roll oddity was in a Michigan courthouse to be arraigned on a charge of criminal sexual misconduct for allegedly assaulting a security guard with his genitals during a July 30 concert in a Detroit suburb.

Manson, decked out in a black T-shirt and matching 3-inch black pumps along with blue sunglasses and his signature white makeup remained silent throughout the court hearing while his lawyer entered a not-guilty plea on his behalf.

Afterwards, Manson signed autographs, posed for photos with fans attending the hearing and even shook hands with his arresting officer, detective Dirk Finley.

Manson's attorney, Walter J. Piszczatowski, said his Satan-loving client is fully aware of the consequences of his alleged behavior and went to great lengths to appear in court as ordered by the judge.

"He's taking it seriously," Piszczatowski told the Associated Press. "He flew in on the red-eye from California during the worst time to fly in the nation's history. Obviously, he's taking it seriously."

While Manson, 32, is used to protests over his deliberately disturbing lyrics, freakish album covers and outlandish on-stage behavior, he's now facing possible prison time for something that tops all that. During a July performance with Ozzfest at the DTE Energy Theater in Clarkston, Michigan, Manson allegedly spit on a 25-year-old security guard named Joshua Keasler, then the G-string-clad rocker supposedly wrapped his legs around Keasler's head and began rubbing his genitals against the guard.

In August, Oakland County prosecutors slapped the Antichrist Superstar with criminal sexual misconduct, a fourth-degree felony that carries a maximum penalty of two years in prison. Manson also faces one count of misdemeanor assault and battery.

Manson flew back to Los Angeles immediately following the arraignment to work on his next album.

Piszczatowski said he believes Manson is innocent of the charges and intends to ask the judge for dismissal. A preliminary hearing has been set for October 9.
