For most people out there, it's shocking but it's true:
The stars did not drop this D-Word upon announcing their separation last week, but it seems inevitable that their separation will soon lead to a legal break-up.
Like we said above, most celebrity gossip followers are surprised by this development.
But at least one individual saw it coming from the very beginning.
Her name is Heidi Bivens and she's a designer who dated Theroux for 14 years, splitting from him not long before the actor got with Aniston in 2012.
According to The Sun, Bivens actually got in touch with the world famous former Friend in order to give her a heads-up.
She allegedly tried to tell Aniston not to get her hopes too high for a bright, long future with Theroux -- because Bivens knew the romance was doomed to end in heartbreak.
"Heidi warned Jen and said, ‘Don’t believe you will have him for good," a friend of of Heather's told the British publication, describing Justin at the time to Jennifer as a "free spirit."
This isn't necessarily a bad thing, of course.
But The Sun source went on to explain that Theorux "hated Hollywood" and believed it to be "vacuous," quoting Bivens, who had said years ago that her ex would never want to "settle" in Tinseltown.
This actually jibes with reports that a major reason why Aniston and Theroux broke up was due not just to distance, but their contrasting feelings for each coast.
One insider has said that Aniston wanted to spend most of her time in Los Angeles, while Theroux preferred New York.
This isn't too imply that Theroux didn't enjoy acting/
He actually may have loved it TOO much, in a weird way.
“Justin would get immersed in his parts and ‘become’ the characters," this same friend of Heather's told The Sun, adding:
"You wouldn’t know where the real Justin was when he was into a role and it would be the case for months on end.
“Heidi found that difficult to deal with and it did cause tension between them."
Could method acting really be the cause of a break-up? We've never dated an actor. So we can't say for certain.
But Theroux did just spend the last couple of years portraying the main character on HBO's The Leftovers.
And, without giving anything away about that series, let's just say it's quite dark and, at times, quite disturbing.
If Justin really did sink himself into the role as much as the above quote states he may have, it would be easy to see how difficult he may have been to live with.
Upon confirming their marriage was over a few days ago, Aniston and Theroux said the following:
Normally we would do this privately, but given that the gossip industry cannot resist an opportunity to speculate and invent, we wanted to convey the truth directly.
Whatever else is printed about us that is not directly from us, is someone else’s fictional narrative.
Above all, we are determined to maintain the deep respect and love that we have for one another.
