ET caught up with the pair on the Oscars red carpet on Sunday, when the longtime couple dished that they're actually currently celebrating meeting one another 10 years ago. Nicole and Keith met at G'Day LA, an event honoring Australians, in January 2005. They married in June 2006, and have two daughters together, Sunday Rose and Faith.
"We celebrate the meeting I hope every day," Keith sweetly told ET about the important milestone.
"We're lucky to have met each other," Nicole added. "We always say that."
Nicole, looking gorgeous in a strapless Louis Vuitton design which she accessorized with a standout red belt, also dazzled wearing more than $7 million worth of Harry Winston diamonds.
"I told all the girls I'm taking mom to the ball," Keith smiled.
Though of course, for the 47-year-old Oscar-winning actress, the Academy Awards are about plenty more than just her dress.
"My daughter's like, 'Wow, I want to go to the Oscars so I could wear a pretty dress,' [but] I'm like, 'Hold on, there's another reason to go,'" she laughed.
"It's wonderful to celebrate fashion, but at the same time it's wonderful to celebrate the work that women do, and it's also good for our daughters and the next generation to be aware of that so it's not just all about the dress, right?" she told ET about the much talked-about #AskHerMore initiative.
