It has been claimed that Bivens she told Aniston: "You won't have him for good."
Bivens was left devastated when Justin ditched her after 14 years together for the former Friends star.
The pair fell for one another after starring in the 2012 movie 'Wanderlust'.
A source claims: "Heidi warned Jen and said, 'Don't believe you will have him for good'.
She told her he was a 'free spirit' who wasn't impressed with the trappings of fame.
"She also claimed he hated Hollywood, thinking it vacuous. She insisted he wouldn't want to settle there.
"It seems her suspicions have now been proved right."
Hollywood was left stunned after the pair announced that they were splitting after two years of marriage with latest reports linking Aniston with former husband Brad Pitt.
The source, who supported Bivens through the break-up, told how that relationship had been in trouble for some time before Justin met Jen.
She claims The Leftovers star's devotion to his work caused problems with their relationship.
"Justin would get immersed in his parts and 'become' the characters.
"It made him a fantastic actor to work with but away from the film sets, he would get very intense and could be difficult."
The source added: "You wouldn't know where the real Justin was when he was into a role and it would be the case for months on end. Heidi found that difficult to deal with and it did cause tension between them.
"Perhaps he thought Jennifer, as an actress, would understand that process and find it easier to cope with in a relationship. But they've clearly had their own problems for some time," claims the source.
In a bizarre twist it is being reported that Aniston, 49, and Theroux, 45, might not have gotten legally married back in 2015.
