Fans got a glimpse of how time flies when Brady wished his oldest son, John "Jack" Edward Thomas Moynahan, a happy birthday on Instagram. Brady shared "all my favorite things about you" in the heartfelt message.

How old is Tom Brady's son?
Brady's son Jack turned 17 on Thursday, Aug. 22, 2024. Jack is the oldest of three siblings, and the only kid Brady has with ex-girlfriend Bridget Moynahan.
Jack was born in 2007, a year after Brady and Moynahan broke up. The star quarterback learned of Moynahan's pregnancy just a few months after he began dating Gisele Bundchen.
"Next thing you know, I found out that Bridget was pregnant with our son," Brady told Howard Stern in 2020. "So that was a very unique time … and it challenged me in a lot of ways, again, to grow up in a different way. It was very hard for my wife to think she fell in love with this guy, and then now this guy's ex-girlfriend's pregnant."
Neither Brady nor Moynahan expected the pregnancy but took it in stride and figured out a co-parenting solution. Bundchen stayed with Brady through this, marrying him for over 13 years before the couple divorced.
"Tom and I made a decision to raise a child together and we both found partners that not only supported us in raising that child but also loved our child as if he was their own," Moynahan told PEOPLE. "I don't think you can ask for more than that. My son is surrounded by love."

Does Tom Brady's son play football?
Brady's son Jack does play football in high school. He plays quarterback for the team, taking after his father.
That wasn't always expected, however. Jack played a bunch of sports growing up and even wanted to be a soccer player.
"I think [the kids are] into watching [football] because of their dad, but … My oldest son Jack really loves soccer," Brady told PEOPLE in 2018. "He wants to be an Olympics soccer goalie."
It's a great joy for Brady to watch his son play quarterback. It played a role in Brady not returning for another NFL season after retiring for the second time.
"Getting out there and watching him play has been so much fun for me," Brady said. "And I don't give a s— how well he does. I just love watching him and seeing him enjoy it with his friends. And, you know, the camaraderie at a young age."
