"10:28pm on 4/30/2021 our family grew by 1," he began his Instagram caption. "My heart is so full and we are ready to do our best to raise good men! To my 2 boys I promise to always love you and to be there for you in every way I can be."
The proud dad also took a moment to praise his wife, Breanne Racano.
"You're the greatest thing that ever happened to me who also gave me two of the greatest gifts I have ever received," the HBO star expressed. "I marvel at what you have done and you are the glue that holds us all together. Not enough words to ever thank and honor you. So for now I'll just say thank you and I love you forever and ever!"

Jerry took to Instagram on Monday, Dec. 7 to share that he and his wife Breanna Racano are expecting their second child.
"It's been a rough year for sure," the 41-year-old actor wrote. "But I am grateful to being adding another little boy to our family. 3 of us becomes 4 us! And I probably lose the rest of whatever hair I have left…"
In line with acknowledging Jerry's thick locks, producer and writer for Entourage Rob Weiss hilariously commented, "Bro youre like 40 w a full head of hair you should make 10 more kids [crying laughing emoji]. Congrats!"
As fans may recall, the proud dad announced Breanna's first pregnancy with son Jacob Michael Ferrara on social media back in Jan. 2019. In the touching post, he wrote, "With the 1st pick in the 2019 draft of life. @breanneracanoferrara and I select: our unnamed BABY BOY!!! It's been a long journey and we both cannot be more excited for parenthood."
He also reflected on his own upbringing—"Growing up without a father means this is the most important job/thing I'll ever do"—and gushed about his wife of three years.
"I could NOT be ready for this without my beautiful pregnant wife," confessed the star. "I pray he gets your height, face, athleticism, charm, intelligence and most important. Your metabolism! 2019 here we come!"
On May 6, 2019, the happy couple shared their now 19-month-old- son with the world, writing, "Everyone!!! @breanneracanoferrara and I are proud to introduce you to our beautiful baby boy... Jacob Michael Ferrara. Born 5/5/19 at 11:52 am. Mom and baby are doing great and I'm still amazed by the strength, Will Power, determination and self belief my wife showed during birth. It's the greatest thing I've ever seen anyone do in my lifetime."
