On Sunday (January 5), embattled shock rocker Marilyn Manson hosted his 56th birthday party in Hollywood that was attended by members of Smashing Pumpkins, Filter, Mötley Crüe, and Falling In Reverse. The Pumpkins’ Billy Corgan and James Iha (who is Manson’s brother-in-law as they are married to sisters Ashley Usich and Lindsay Usich) were both in attendance, despite Manson once saying that Corgan looked like Charlie Brown. Filter’s Richard Patrick, Falling in Reverse’s Ronnie Radke, and Mötley Crüe’s John 5 were also there to celebrate Manson’s birthday, with the musician disclosing to the crowd that he was also celebrating four years of sobriety that evening.
