Dorsey shared a sweet message about his son on Instagram in January, writing, "This little boy ... man ... I couldn't be any prouder of someone. At such a young age, he's endured more than anyone should at 5 years old.
"Without even fully realising it, he lives the #keeppounding mantra every day with his resilance [sic]," Ryan continued in his post. "You're so strong, so brave, and so kind. I will always be proud of you and we will always #keeppounding b/c that's all we can do."
And earlier that month, Dorsey had shared a tribute to Rivera on what would have been her 34th birthday. The couple were married from 2014 to 2018, welcoming son Josey in September 2015.
Dorsey wrote, "Just as surreal as it is real that you're gone. If that makes sense, but none of this still makes any sense ..." on Instagram alongside a black-and-white photo of the family of three. "34 ... I could just hear you saying "Ah, I'm old AF now!" Ha ... Rest easy old lady ..."
Dorsey also honoured his own mother over the weekend with a sweet photo of her with Josey.
"Happy Mother's Day Grammy…Thanks for all the support, unconditional love, all the help, your patience, thoughtfulness, and everything you do. We love you," the actor wrote.
