Tom Brady is kicking off another celebration in his family.

The former NFL star celebrated his son Jack on his 19th birthday by sharing a heartfelt tribute to the teen—whom he shares with ex Bridget Moynahan—on his special day.  

“Happy 19th birthday, Jack!” Tom wrote alongside a carousel of photos in an Aug. 22 Instagram post. “Aug 22, 2007 is a day I’ll never forget, because that’s when you showed up and stole my heart (and my sleep… and my patience… hahahaha).”

“you’re kind, thoughtful, empathetic, and full of love!” he continued. “And I’m so proud of who you have become. You fill my heart with so much joy and I’m blessed to be your dad. I cant wait to see what’s next.”

The seven-time Super Bowl champion—also dad to son Benjamin, 16, and daughter Vivian, 13, with ex Gisele Bündchen—gave a glimpse into his relationship with Jack in the post. Indeed, Tom shared a series of sweet photos of some of their father-son adventures, including shots from outings to sports games and their recent family trip to Alaska.

The Fox Sports host also proved he’ll always be there to cheer Jack on. After all, Tom posted multiple photos of  the 19-year-old playing basketball, showing off his skills on the court.

Additionally, Tom's post to his eldest featured pics from Jack’s high school graduation, which the 49-year-old called “one of the proudest days of my life” at the time.

“Watching Jack walk across the stage, and graduate into the next chapter of what’s already an impressive life,” Tom shared in a June 13 Instagram post alongside family photos from the big day. You are an amazing son, brother, grandson, nephew, and friend amongst many other things.”

And while Tom has yet to share details about his son’s plans beyond high school, he’s praised Jack’s undeniable athletic ability.

"Unfortunately he jumps as high as I do," he joked at the Fortune Global Forum in November 2024. "But I tell him, 'Dude, you're gonna be a stud.' I said, ‘Wait till you hit your growth spurt, you're gonna be jumping higher, you're gonna be dunkin’.’”

As for whether he wants his son to follow in his footsteps into the world of professional sports someday, Tom shared, “Who cares? But I want him to know that his dad's got his back."

Gisele BĂźndchen shared this family photo on Instagram on Tom Brady's son Jack's 14th birthday, writing, "Happy birthday Jack! We are all so lucky to have you in our lives. Thank you for being the best big brother in the world. We love you soooo much!"

While wearing his Christopher Cloos x Brady sunglasses, Tom celebrates his Super Bowl win with daughter Vivian during the Tampa Bay Buccaneers boat parade. 

After winning his seventh Super Bowl, the Tampa Bay quarterback celebrated with his daughter Vivian.

Tom snuggled with his kids John "Jack" Moynahan (with ex Bridget Moynahan), Vivian and Benjamin in this adorable photo snapped by Gisele on Father's Day.

Brady went from quarterback to coach with his son on the beach, writing on Instagram that he's "#dadsfavoriteworkoutpartner."

Gisele shared this adorable photo on Instagram of Tom giving his son a kiss on the forehead.

The whole Brady-bĂźnch posed together at the Mercedes-Benz in Atlanta ahead of the Super Bowl LIII, which the Patriots later won.

Tom lurked as Pennywise the Dancing Clown in a window behind his family as they celebrate Halloween in 2018.

As Tom geared up for another football season, he stopped to give his daughter a little love and clearly this one has her dad's full attention.

In July 2018, the Brady bunch headed out of town for a family vacation and they couldn't look any happier on their horseback riding adventure.

Tom celebrated Father's Day with a family dinner and lots of silly photos with his younger son, Ben. 

There's nothing sweeter than seeing the greatest quarterback of all time (he has seven Super Bowl rings) get smothered in love by his three kids.

Even though it was springtime, Tom bundled up with Ben for a fun day outside...complete with a little training.

Tom Brady as the Easter bunny? Who would've guessed?!

The super sweet family was all smiles during one of Brady's episodes of Tom vs. Time.

After playing in another Super Bowl, Tom took a little break with his family, complete with burger time and selfies.

Even though the Patriots lost the 2018 Super Bowl, Tom had his support squad ready and waiting to cheer him up.

Ahead of Super Bowl LII, the Patriots QB posed for pictures with his whole family including Gisele and oldest son Jack, second-born Ben, and daughter Vivian.

The New England Patriots quarterback showed his second oldest son a little love on his birthday in December of 2017, writing, "Happy Birthday to the sweetest 8 year old boy a mom and dad could ever ask for! So filled with love and joy! We are so proud of you Benny! And you shine a light that brightens our lives every day! We love you."

Vivian was the ultimate sous chef as her dad made her biscuits before Thanksgiving and really, what can't Brady do?

The dynamic duo of Tom and Ben spent a November day swinging in a hammock together and we really wish we had some R&R like this in our near future.

Leave it to Tom to teach his son more than just football. 

The Brady crew rolled around in the grass and enjoyed spending time together in June 2017 and it really does look like they are having a blast.

When the Patriots headed back to Boston for their parade celebration after their 2017 Super Bowl win, Tom brought Ben along for the ride making him the coolest dad around.

Winning the Super Bowl in 2017 was great, but getting to celebrate with your daughter on the field is priceless. 

In 2017, Vivian gave her dad a big good luck kiss before he headed out for a game. Seriously, these two are so stinking cute.

Tom's fans span near and far, but his biggest fans are his three kids and their "Brady" jerseys continually make us love them even more as a unit.

Decorating the Christmas tree is twice as fun when you have your precious daughter helping you out...especially when she's dressed as a fairy!

The football player loves to spend his off time with his adorable kiddos at the beach and we totally approve.
