Michelle and David have been married for 27 years
The couple tied the knot in 1993 and Michelle previously revealed that she never takes her husband "for granted".
"I chose really well with David. I got really lucky," Michelle told Parade magazine in 2012. "I never take him for granted.
"I’ve never met a person who has more integrity than my husband. I respect that. There’s his humour and intelligence, too, and he’s really cute, all those things—but if you don’t respect your partner, you’ll get sick of him."
Michelle and David share two children
The couple share two children together, son John and daughter Claudia. Michelle was in the process of adopting Claudia before she even met David.
"When she came, he and I had only been together for about two months," the Oscar nominee told Good Housekeeping in 2007.
"So we had this child with us right away, and… I really got to see him in a situation that certainly would separate the boys from the men. Obviously, he really rose to the occasion."
