After calling Diaz his “queen” and himself a “lucky man,” the musician wrote, “Today, it’s a very Happy Birthday to my beautiful wife, best friend, best partner in everything, ride or die, greatest Mom to our little girl, @Avaline wine boss, family chef, advisor, collaborator and everything else. You do it all.”

Joel left heart emojis in the comments section at the time.

As for his own relationship, Joel and Nicole, 42, tied the knot in December 2010 after four years of dating.
