Five years after their divorce, Billy Bob Thornton has nothing but kind words to say for Angelina Jolie and her growing family.

“I think she was always meant to be a mother in so many ways,” Billy Bob tells Extra. “I’m just so happy for her.”

Billy Bob and Angelina split in 2002, shortly after she adopted Maddox, now 6, from Cambodia. Their divorce was finalized a year later, and although the actor was listed as Maddox’s father, Angelina received sole custody, and Brad Pitt officially adopted Maddox in 2006.

“I’m happy for the kids to have a mother like her and a father like him,” Billy Bob, a dad himself of four, says.

The 52-year-old is left even more “astounded” by his ex-wife’s goodwill and humanitarian efforts.

“I’m astounded that somebody has that kind of passion and that much energy for something that actually does affect people and help people out,” he says.
