Ben Affleck thinks his wife is the "best person in the world".
The Argo star and director has praised Jennifer Garner for supporting him and always being there for him.
The couple have been married for eight years and share three children, Violet, seven, Seraphina, four, and Samuel, 11 months.
The 40-year-old actor told the crowd while accepting his Best Director award at the Director's Guild of America Awards: "I have to just thank my wife for being the best person in the world. I love you.
"I don't need to look at the teleprompter to know why I want to thank you. I want to thank you because I love you."
Affleck also opened up about his hopes for their family, according to People.com, and said: "I want our daughters to break boundaries."
He recently revealed he doesn't want his children to follow in his and Garner's footsteps in Hollywood because he already thinks they are exposed too much.
"I would do whatever I could to discourage that. My kids have enough issues of being exposed in ways that I don't want them to be exposed, in magazines and shows and stuff," he said.
But he previously revealed he thinks his working life is "richer" because of his family life.
He explained: "They're the most important people in my life. Family is a wonderful thing, but it doesn't mean you can't do other stuff in your life.
"In fact, having a family makes whatever other thing you have that much richer. If it was just me, I'd be home alone and think, 'Well, something good happened at work', but it's much nicer to share it with people you love.
"I think any time you become a richer person you have more substance. I hope that happened to me with having a family, but you never know!"
