Jennifer Aniston: boozehound homewrecker. It’s a brand new day! Us Weekly’s cover story this week is all about how Jennifer Aniston “pulled an Angelina” with Justin Theroux, in what I hope will be the beginning of an exhaustive six-year journey where every nuance of Jennifer Aniston’s homewrecked relationship is dissected in the press. Fingers crossed. Anyway, it doesn’t seem like Us Weekly has much new information – their sources are still claiming that Aniston and Justin began their relationship while working on Wanderlust last fall, and that they were seeing each other in secret for months and months while Justin was still officially “with” his girlfriend of 14 years, Heidi Bivens. Us Weekly gets some bitchy quotes from a “source” close to Heidi too:

Jennifer Aniston sure knows how to flip the script. The 42-year-old star fell hard for costar Justin Theroux on the Georgia set of Wanderlust last fall, and nothing was going to get in her way, not even Theroux’s 14-year relationship with live-in girlfriend Heidi Bivens.

“Jen went after him,” a set source tells the new Us Weekly, out now; as Wanderlust’s shoot continued, Aniston and hunky Theroux, 39, began having secret trysts at her temporary digs, a huge, secluded house on Georgia’s Lake Rabun.

Charmed by Theroux’s quick wit, his edgy downtown hipster style and impressive background as the screenwriter behind Tropic Thunder and other hits, Aniston overlooked her secret beau’s relationship status, a Theroux insider says: “Jen wanted Justin and it didn’t matter that he was already with someone.”

Fast forward to March of 2011 — when Theroux abruptly ended things with fashion stylist Bivens, 35, who moved out of their NYC apartment in June. Blindsided and hurt, Bivens “didn’t know Aniston was the catalyst” behind the split, the source says, “until now.”

And, yes, the bitter irony — Aniston’s husband Brad Pitt infamously left her for Angelina Jolie six years ago after falling in love on set — is lost on no one. “It’s amazing she would go for an attached guy after what happened to her.”

Adds a Bivens insider: “It sucks when your ex dates the most famous woman in the world so soon after a breakup.”

For much more details on Aniston and Theroux’s shocking fast-track romance and the fallout — how Theroux’s ex thinks it’s “tacky,” how he’s “obsessed” with becoming a superstar, and more — pick up the new Us Weekly, out now!

I have mixed feelings about Jennifer and Justin’s relationship, honestly. Part of me thinks it’s hilarious that Aniston just torpedoed her “good girl/wronged woman” image after years and years of careful maintenance. Another part of me things that this is one of the smarter moves Aniston has made, long-term. While the “good girl” image was profitable for her and her status as some sad-sack, tear-soaked wronged woman guaranteed that she would always be relevant from a tabloid-media perspective, the woman is in her 40s, and she’s no longer being the virginal good-girl roles. This new image – wanton, liquor-soaked homewrecker – might allow her to actually change up her career and change how she’s treated in the press, like the Patron Saint of Lonely Cat Ladies.

As for Justin… is anyone else wondering about “how he’s ‘obsessed’ with becoming a superstar”? Justin just moved to Aniston’s agency, CAA, and he’ll be getting so much press now that he and Aniston are a thing. I wonder if he’ll like the attention, like John Mayer did? Theroux seemed to be fine with this official boyfriend rollout, so I think he’s going to put some time into this relationship and see how much he can get out of it. Maybe a year, tops.
