Jennifer Aniston, Justin Theroux(CP)

Jennifer Aniston may be sticking to her trademark rom-com characters on the big screen but in her private life, it seems she's set to take on a very different role.

For six long years, she's been known as "Jennifer the Victim," left to mourn her four-year marriage to Brad Pitt after he was seduced and stolen out from under her by the venomous vixen Angelina Jolie.

Now almost overnight, she's become "Jennifer the Villain," accused of pursuing her "Wanderlust" co-star Justin Theroux, who was in a 14-year-relationship with his live-in girlfriend Heidi Bivens when the pair met on set.

"Jen wanted Justin and it didn't matter that he was already with someone," a Theroux insider tells the US Weekly.

While Aniston's publicist is already working overtime trying to shift the tides as they turn against his client (a "source" close to Aniston told People yesterday that "Jen would never hook up with a guy who has a girlfriend") the damage may already be done.

Or at the very least, it may finally be enough to put an end to the woe-is-me Aniston stories which have become almost as tiresome as Britney Spears articles beginning with "Oops, she did it again!"

The new home-wrecker label also brings up questions about the breakdown of her marriage to Pitt, the circumstances of which have arguably made Aniston the superstar she is today, keeping her in the headlines year after year and making her a fan favourite with those who feel a connection based on her misfortune.

But if she really was left crushed when Pitt left her for his "Mr. and Mrs. Smith" co-star, and if she really was as betrayed as we've been led to believe having to watch Brangelina build their happy family all these years, would she really go out and do the exact same thing to another woman?

On the heels of his breakup with Biven, Theroux and Aniston have been photographed sporting matching gold bands and the cozy couple has willingly cuddled for intimate photos they knew would get passed around for public consumption. Could a woman who was burned so painfully and so publically all of a sudden turn around and willingly inflict the same emotional torture on another? It just doesn't add up.

So perhaps the breakdown of Aniston's marriage to Pitt didn't exactly happen as we've been sold? Were there issues far beyond Jolie, such as rumours the "Friends" star didn't want kids, which were really to blame?

Much of Aniston's superstardom stems from her relationship with Pitt and the legacy of his abandonment. Her fans have stuck by her largely in part because they see her as a victim who continues to weather the storm. It's unlikely they will be so loyal if their hero is proven to be a home-wrecker.
