Shock rocker Marilyn Manson and actress Evan Rachel Wood have split.

The couple broke up after a bitter argument on October 23 over Evan’s 21-year-old brother, Ira, who had been living with the celebrity pair.

“Evan owned the house and didn’t want her unemployed sibling living on the street,” a source tells Star. “It was the tipping point. Evan was fed up with how controlling and emotionally abusive Marilyn was.”

Marilyn and Thirteen star began dating in December 2006, following his split from then-wife, burlesque star Dita Von Teese.
