Now, as the couple celebrates Tatum's first milestone, it's the perfect time for them to reflect on their first 12 months of parenthood. Shortly after Tatum’s arrival, Paulina said that finally being able to hold her son was the “happiest day of our entire lives.” "It's just unbelievable,” she gushed to reporters. “Dustin's the best dad, he's my best friend. He's been so supportive with me and we're just there for each other. I couldn't be happier for him."
