Jennifer Aniston as the Other Woman? Justin Theroux's girlfriend Heidi Bivens moves out

heidi-bivens-justin-theroux.jpg Jennifer Aniston is arguably the most famous jilted woman of recent years. But now, depending on which anonymous gossip-column source you choose to believe, she may be the Other Woman.

Aniston has lately been linked to actor and writer Justin Theroux, and their budding romance has apparently hastened the end of Theroux's relationship with his long-time girlfriend, costume designer Heidi Bivens. Page Six reports that Bivens moved out of the home she shared with Theroux last weekend and cites a source saying she was "blindsided" by Theroux's relationship with Aniston.

"She and Justin had been together for years, they had a home," the source says. "Then he met Jennifer and everything changed."

Aniston and Theroux met while filming the movie "Wanderlust" last year and were first spotted out together in May. Their reps at first said they were just pals, but they've become more and more of an item in recent weeks.

It's here where we draw the parallel between Aniston's current situation and that of her, then-husband Brad Pitt and Angelina Jolie back in 2005. Pitt and Jolie met while filming "Mr. and Mrs. Smith," and the rest is well-documented magazine-cover history.

Neither Aniston nor Theroux has commented publicly on their relationship. A friend of Theroux's, however, insists to Page Six that "Things were already over between him and Heidi before he got close to Jen." Us Weekly, meanwhile, quotes an "insider" who says Theroux "broke it off for good" with Bivens in March, despite the fact that they continued to live together.
