After many unsuccessful relationships, Jennifer Aniston finally found love with her "Wanderlust" co-star, Justin Theroux, but there has been ongoing ambiguity over when exactly their relationship started and when the actor split from his long-term love Heidi Bivens.

The actress, who is upset at being portrayed as a home wrecker, is said to have had an emotional heart-to-heart talk with beau's ex-girlfriend to finally clear the air between them.

According to Grazia magazine, in a bid to set the record straight, Aniston met with the costume designer in a New York hotel.

They talked over a glass of wine and assured Bivens that she never got together with Theroux until he was single. "Jen has always been sympathetic to Heidi because she has heard from Justin just how devastated she is about their break-up," the source said according to the Daily Mail.

"But Jen has always been adamant that their relationships did not cross over," the source added.

"Jen told Heidi that she understands what a painful time she has been going through and explained that she wanted her to know, hand on heart, that she would never steal another woman's man. Heidi apparently got quite tearful during the meeting, as it was understandably a lot of take in," the source shared.

Aniston and Theroux met on the set of new film "Wanderlust" last autumn but the two were not romantically linked until late May this year. Bivens confirmed in a statement via her publicist that she moved out of their home after fourteen years with Theroux and it was a week after Aniston and Theroux were first photographed together at the MTV Movie Awards after-party.

Since then, the couple became inseparable and they are now living together in a $6million New York apartment.
