Jennifer Aniston and Justin Theroux shot down breakup rumors when they were spotted on an outing this week, and it appears that things have taken a turn for the best, with insiders revealing that the engaged couple have finally settled their wedding plans.

Aniston and Theroux split rumors went into high drive earlier this year when they postponed their wedding that was slated for this summer. Yet, despite earlier bad signs, it appears the couple simply wanted to swap seasons, opting for a winter wedding instead. Deciding on a December wedding to ease their busy work schedules, a source close to the couple said that the decision was a huge “breakthrough” because “the main source of uncertainty has been removed.”

Not only did Aniston and Theroux settle on the season, but they also decided on a location, which was apparently an even sorer subject when discussing marriage plans. “Jen and Justin have gone back and forth on where to marry and whether to have a destination wedding so many times,” the insider explained. “Jen has always made it clear L.A. was her first choice and Justin has compromised and agreed to marry in California,” the source added.

“Justin’s reservations with L.A. are well known and he wanted to marry on the East Coast where his friends and much of his family is based, where he proposed to Jen and where he feels most comfortable,” the insider continued. While Theroux calls New York home, Aniston has made no secret of her love for California, and the two have found it difficult to reach a compromise on their hometown.

“Contrary to popular opinion Jen does not hate New York. She studied there growing up, but it’s now become too intense for her,” the source revealed. “She has made it clear how much it would mean to her to get married near where they now live and where she is happiest and feels most settled.” Aniston and Theroux were initially believed to be walking down the aisle at the $21 million Bel Air estate that they have been tirelessly renovating, but have now, apparently, decided on a different setting for their I Dos.

“They won’t [marry] at their recently renovated Bel Air mansion, but will likely use their home to host an intimate reception,” the insider explained. Aniston and Theroux have apparently bonded while building a home together, often frequenting antique shops to furnish the sprawling estate with meaningful details.

News that Aniston and Theroux have made progress with their marriage plans comes as a relief to the actress who feared public humiliation if the engagement fell through. Although she was hoping to become Mrs. Theroux by August, something tells us that Aniston won’t be complaining about the date when she finally says "I do."
