Matt Damon is known for being a doting dad -- he even recently had a family day at Disneyland for his daughter Gia's seventh birthday -- and the father of four is opening up to ET about how much his kids have changed him.
ET caught up with the 44-year-old actor at the grand opening of trainer Jason Walsh's Rise Nation fitness studio in West Hollywood, where he revealed that being a dad makes him "feel really lucky."
"I think everything changes in little wonderful ways," he told ET. "My whole life opened up when I became a dad."
"I'm very much on the receiving end of all the good stuff," he added.
Damon has an excellent partner in parenting in his wife of almost a decade, Luciana Barroso, and after all these years together, The Martian star is still gushing over her.
It was love at first sight for the pair -- even if Damon still isn't sure he believes in that sort of thing. "She definitely struck me. It was like the room lit up or something," he said of the moment he met his wife. "I don't go in for that kind of thing, but what can I say? It happened to me."
Their first romantic moment was equally as sweet. The Boston native told ET that though it wasn't their first official date, a night together while he was working in Prague was very special. "We went on a walk in Prague," he shared. "That wouldn't have been our first date, but that was the first thing we both agreed was actually more romantic than we expected -- a long walk on a warm night."
So how will they be celebrating their 10th anniversary this December? Damon will be on the set of the next Bourne movie, which Walsh is helping him to train for.
"Hopefully they'll give me the night off so we can go get dinner," he said. "December 9 is not a great anniversary persay, because it's normally a time when everyone is working, so we usually try to figure out something fun and special to do. If I can get a couple days off I'll figure something out."
