This heartwarming introduction to the family's new canine companion comes just a few days after her father-in-law, Kirk Douglas, died at the age of 103.
The three-time Oscar nominee and silver screen legend passed on Feb. 5, and there was an outpouring of love and tributes honoring his life and legacy from some of Hollywood's biggest stars, including his son, Michael Dougas, and Zeta-Jones herself.
"To my darling Kirk, I shall love you for the rest of my life. I miss you already. Sleep tight…" she wrote on Instagram, alongside a black-and-white photo of her giving the legendary actor a kiss on the cheek.
On Friday, Kirk was laid to rest at the Pierce Brothers Westwood Village Memorial Park and Mortuary in Los Angeles.
