They were pictured sharing a kiss as they walked out of a restaurant pushing their newborn son, Cardinal, in a stroller.
The couple welcomed Cardinal in March.
“We are blessed and excited to announce the birth of our Son, Cardinal Madden. He is awesome and We are all so happy he is here!” they wrote in a joint Instagram post at the time.
“For the kids safety and privacy we won’t be posting any pictures- but he’s a really cute.”
Diaz and the rock star tied the knot at her Beverly Hills, Calif., home in January 2015 after dating for less than a year. They later welcomed Raddix — via surrogate — in January 2020.
