In the statement they released when they announced their split in February, former Hollywood couple Jennifer Aniston and Justin Theroux said: 'We look forward to continuing our cherished friendship.'
According to Life & Style, the pair's split has become far from amicable, with the publication explosively claiming the two got into a heated fight.
'Jen confronted Justin and lit into him,' the source says. 'She keeps seeing him out with young models and actresses and she's told him, 'Stop humiliating me!''
In recent weeks, Justin, 46, has been spotted out with a slew of women, including Selena Gomez, models Erika Cardens and Petra Collins, all 25, as well as actress Aubrey Plaza, 33.
Jennifer Aniston, 49, 'feels like Justin's traded her in for a bunch of newer models,' an insider told Life & Style.
'She considers it the ultimate insult,' the source added.
Life & Style's explosive report adds that it wasn't just the age of Justin's new friends that Jen is finding humiliating, but his constant partying has made her look bad.
'Jen believes they both should have laid low for the first few months and given their relationship a mourning period,' a friends tells the publication.
'Instead, Justin's been acting like a man who was just let out of prison.
'Jen feels betrayed.'
The couple announced the end of their seven year marriage in February.
