"Manson, whose real name is the marginally more dull Brian Warner, had been dating gorgeous Dita for seven years before they married."
Nope. It's well documented that Dita turned up at Manson's house on January 5th 2001 (his 32nd birthday) with a bottle of absinthe, and they'd been together since that date. As they got married on December 3rd 2005, that makes it just shy of 4 years 11 months between dating and marriage.
I guess mistakes like this are bound to happen if all you do is re-write articles from the New York Post's 'Page Six' column - tellingly, they also made the same blunder.
