Billy Bob Thornton "never felt good enough" for Angelina Jolie.
The 'Bad Santa' star married the 41-year-old actress in 2000, following just a two-month courtship, and he's not surprised their relationship hit the rocks shortly afterwards and they divorced in 2003 because he wasn't prepared to change himself to suit her.
Speaking in the November issue of GQ magazine, he said of the beauty: "I never felt good enough for her. I'm real uncomfortable around rich and important people. I like how I am."
Despite their divorce, which was finalised just three months after the actress adopted her first child Maddox, 15, from Cambodia, Billy and Angelina still try to find time to talk to one another.
However, the possibility of a romance reunion between them has well and truly sailed now, as the 61-year-old actor - who has been married six times - is wed to his longtime partner Connie Angland, who is the mother of his 12-year-old daughter Bella.
The couple dated for years before they eventually tied the knot in 2014 because he didn't want her to be seen as a number.
He explained: "I didn't want her to be called number six."
Angelina, on the other hand, went on to strike up a relationship with Brad Pitt after they fell for one another while starring opposite each other in the 2005 film 'Mr. and Mrs. Smith'.
Brad was married to Jennifer Aniston at the time but, despite denying they had an affair, Angelina was blamed for their divorce.
The couple refused to comment on the status of their relationship until the following year when they announced they were expecting a baby girl - named Shiloh, now aged 10 - together.
They then went on to adopt two more children Pax, 12, and Zahara, 11, together, before welcoming their twins Vivienne and Knox, eight, into the world in Nice, France, in 2008.
Following six years of dating, the couple announced their engagement in April 2012 before eventually tying the knot at their estate Château Miraval in Correns, France, in August 2014.
However, their marriage didn't last long as Angelina recently filed for divorce and requested physical custody of their children.
The 'By the Sea' star set the ball rolling in September after Brad allegedly got into an argument with Maddox on board a plane.
The 52-year-old actor was accused of child abuse but, following weeks of extensive investigations carried out by social services, he was cleared of the allegations and the case was closed.
