Previously, third party rumors in their marriage circulated when they did not celebrate their first wedding anniversary openly. Aniston was speculated to have her old love with ex-husband Brad Pitt sparkling again. But the rumor was proven to be wrong, as Pitt marriage with Angelina Jolie remains strong.

This time the third party is related to Theroux's old flame, Heidi Bivens, according to Radar Online. Biven was his girlfriend for 14 years before Theroux dumped her for Aniston. It seems he still has a love for Biven.

Lately, Aniston expressed her disapproval of her husband's holiday home in Hawaii. She said the place is boring while Theroux loves it. However, inside source said the real issue is because of Biven.

"Jen isn't a big fan of Hawaii, she only went there because Justin begged her. He still owns his place on Kauai's north shore and feels like its paradise there, but she finds the place boring," the source says. "Not only is it too rustic for her tastes, it's also synonymous with his time with Heidi."

Aniston prefered Mexico as holiday's destination and force him to buy property there. But Theroux does not like anything about Mexico, so they have a fight over the issue.

On the other hand, Heidi Biven's mother, Marilyn disclosed about the truth of how Justin betrayed her as reported by The Inquisitr. She claimed that Heidi had a hard time moving on and finding a new boyfriend because of the lies.

Meanwhile, Aniston is still a popular actress. In a recent interview with TMZ, NBA player Chandler Parsons admits that his first choice for co-star in a romantic comedy film when he ends his NBA career is definitely Aniston. "I've always had a thing for Jennifer Aniston," he said.

Aniston and Theroux married on Aug. 5, 2015 after three years of engagement. They held the ceremony at Bel Air estate which they own together.
