Michael Douglas and Catherine Zeta-Jones’ Kids, Daryl and Carys, Are All Grown-Up!

Time really does fly!

It seems like just yesterday that Michael Douglas and Catherine Zeta-Jones' kids, Daryl and Carys, were barely coming up to their parents' knees.

But in a new photo posted on Instagram by proud mama Catherine, it's very apparent their children are little kids no more!

The happy family were spotted making a rare appearance together in Jerusalem on Thursday, June 18. As stated in Catherine's caption, she and her children were there to support Michael, who was honored with the $1 million 'Genesis Prize' at the second annual Genesis Prize Awards.

And it's a pretty big deal considering it's known as the 'Jewish Nobel Prize'!

Congrats, Michael!
