"I have a story and it's kind of embarrassing," she said. "My husband and I drive up. It's a Sunday. It's a beautiful day, there are no cars around and we thought, OK, we're on time. We're on time for once."

Anne added, "I go, 'Surprise!' And he goes, 'Yeah, you've got to come in.' Matthew turns around and goes, 'Party was last night.'"

McConaughey then told the 'Les Misérables' actress and her hubby to come in for a drink. "Matthew said, 'Come inside. Let me pour you a glass of wine,'" she recalled, "And then Matthew looks at me, very deeply, and says, 'Hey, we can be upset about this. We can be mad about this. Or we can go with it. And we can have a great story.'"

"And that glass of wine led to the first bottle - I stopped counting after four," she continued, "And then I went with him to someone's surprise birthday party that night that I crashed. And you know what? It was a great story and a lot of smiles because of it... You were so good to me and Adam."

That is a good story!
