"She's dealing with a lot of stress and pain, and dealing with it in, I think, a magnificent way," Garber, who officiated Garner and Affleck's 2005 wedding ceremony, told ET on the red carpet for the Vanity Fair Oscar Party.
"I've always found her to be incredibly authentic. It's part of why people, I think, are drawn to her, because she is real," he gushed. "She also has a great capacity for love. You know, her children are her passion. And so, all that said, she's dealing with the situation, I think, miraculously."
The DC's Legends of Tomorrow star admitted that although he has only read "snippets" of the Vanity Fair interview, Garner is very pleased with the way the article turned out.
"I talked to her yesterday," Garber explained. "I saw her yesterday, and she's so happy about it and, it's a beautiful, beautiful cover. And I'm just thrilled that they are -- that Vanity Fair -- is honoring her."
