Jennifer Aniston and husband Justin Theroux are allegedly talking about getting a divorce just a few weeks after tying the knot in a secret wedding.

According to new rumors, Justin Theroux is allegedly cheating on Jennifer Aniston with his "The Leftovers" co-star, Margaret Qualley.

"Apparently, the honeymoon stage for Theroux and Aniston is over, although it never really began - just a few short days after their wedding Justin flew back to Texas to work on Season 2 of 'The Leftovers,'" Celeb Dirty Laundry reported.

"Sources close to the couple tell In Touch Magazine that Jennifer Aniston is miserable with her marriage - and it is not turning out how she thought that it would at all. Jennifer Aniston reportedly asked Justin to have filming of the HBO drama moved to Cali so that they can be closer together, but it doesn't look like that is going to happen," the article continued.

Even before rumors about Margaret Qualley and Justin Theroux came out, there have been sources who claimed that Jennifer was not happy in their young marriage.

"Now Jen has told friends that she and Justin were already on a break that was not of her choosing," an insider reportedly told Life & Style magazine, as previously quoted by Hollywood Life.

"Jen thought finally having that commitment would change Justin for the better, and get him to hunker down and make her - and their life together - a priority. It's not working out that way. She's told a few of her closest pals that she feels like Justin dumped her."

There have been rumors that Jennifer Aniston and her husband are in the process of adopting a baby. There is no information yet as to how they would go about the adoption now that the couple is purportedly on the verge of a divorce.

"She can't even fake the happiness anymore," the source said. "Jen is wondering if she made the biggest mistake of her life by marrying Justin, but she's still vowed to go through the adoption."
