Anyone know why Dita broke it off with Marilyn Manson?

Answer 1

It is rumored (read: not confirmed) that Manson grew too close to co-star and friend, actress Evan Rachel Wood. The two have been friends ever since Manson asked Wood to appear in his upcoming horror movie "Phantasmagoria: The Visions of Lewis Carroll". She also posed for a watercolor painting that he did.
However, neither party has confirmed this.
