As fans know, sources claim that Aniston, 48 leaned on Pitt, 52, for 15 months before she split with Justin Theroux, 46.
Meanwhile, Jolie, 42, and Pitt have still to conclude their own divorce after he infamously left Aniston for his Mr And Mrs Smith co-star.
Although Aniston's publicist denied the report, insiders snitch Pitt has been her "shoulder to cry on" since her relationship with Theroux imploded.
As Radar readers know, the Friends star confirmed her breakup with Theroux on February 15, 2018, and there has since been shocking claims the two were never even legally married in the first place!
The couple released a joint announcement which read, in part, "In an effort to reduce any further speculation, we have decided to announce our separation. This decision was mutual and lovingly made at the end of last year.
"We are two best friends who have decided to part ways as a couple, but look forward to continuing our cherished friendship….Above all, we are determined to maintain the deep respect and love that we have for one another."
Radar told you first that Aniston and Theroux were breaking up and detailed their many issues.

Aniston celebrated her birthday with a party last weekend with Theroux nowhere to be seen.
