Shock rocker Marilyn Manson's marriage to burlesque star Dita Von Teese is over after just a year, according to US reports. The former Playboy model and dancer, real name HEATHER RENEE SWEET, filed for divorce before Christmas (06) but has been unable to find Manson to serve him with the papers, according to the New York Post. Sources claims Von Teese, 34, cited "irreconcilable differences" as the reason for separation, adding that Manson's alcohol use was a factor. One friend tells Post gossip column Page Six, "She tried to tell him she was divorcing him, but she can't even get him on the phone. She's moved out of the house and he hasn't even noticed." Manson, real name BRIAN WARNER, wed Von Teese in December 2005 after a seven-year courtship.
