5 Shocking Ways Tom Brady's Son Jack Is Already Towering Over His NFL Legend Dad

As of December 2025, the eldest son of NFL legend Tom Brady and actress Bridget Moynahan, John "Jack" Edward Thomas Moynahan, is no longer just a celebrity child; he is a towering 18-year-old athlete who is sparking major speculation about a future career that might not even be in football. Recent photos shared by NBA star Karl-Anthony Towns have sent the internet into a frenzy, revealing that Jack has undergone a massive growth spurt, now visibly taller than his 6-foot-4-inch father. This sudden visibility, coupled with his high school athletic pursuits, has positioned Jack as one of the most talked-about young athletes in America, navigating a complex co-parenting dynamic while seemingly charting his own course away from the quarterback legacy of his famous dad. From his surprising height to his close bond with his "bonus mom," Gisele Bündchen, here is the complete, updated breakdown of everything you need to know about the young star.

The Shocking Growth Spurt and NBA Aspirations

The biggest news surrounding Jack Moynahan in late 2025 is his physical transformation and a clear tilt toward basketball, a sport he seems to be excelling in.

Taller Than The GOAT

For years, fans wondered if Jack would inherit his father's athletic build. The answer arrived in stunning fashion. Recent photos show Jack standing visibly taller than his legendary father, Tom Brady, who is 6 feet 4 inches tall. This "shockingly tall" stature immediately shifted the conversation from football to basketball.

From Ball Boy to Basketball Prospect

While Tom Brady often shared photos of Jack playing football—and Jack even served as a ball boy for the Tampa Bay Buccaneers in 2021—his passion appears to be multi-sport. Jack plays football (Quarterback/Running Back), Lacrosse, and Basketball in high school. However, the speculation about a professional career has centered on the court, not the gridiron. In late 2025, Jack was photographed working out and spending time on the basketball court with New York Knicks star Karl-Anthony Towns (KAT). This high-profile training session fueled rumors that the 18-year-old is seriously pursuing basketball, where his new height would be a significant asset.

A "Very Good Student" Finishing High School

Despite the intense athletic pressure that comes with the Brady name, Jack is also noted for his academic focus. His father has referred to him as a "very good student" who is prioritizing his education as he finishes his final year of high school. With an expected graduation in 2026, the college recruitment process for the multi-talented athlete—whether for football, basketball, or academics—will be a major story to watch.

The Harmonious Co-Parenting Dynamic and "Bonus Child" Status

Jack's family life is perhaps the most unique aspect of his public profile, representing a successful, though initially challenging, co-parenting arrangement between three major public figures.

Bridget Moynahan: A Private and Dedicated Mother

Bridget Moynahan, an accomplished actress, has always maintained a relatively private life for her son, especially after the high-profile nature of her split from Tom Brady. Despite the initial media frenzy surrounding the unexpected pregnancy and subsequent birth, Moynahan and Brady have consistently demonstrated a commitment to co-parenting Jack effectively, ensuring he has a stable and loving environment with both parents. She often shares rare, sweet moments of their time together, maintaining their tradition of attending events like the US Open.

Gisele Bündchen: The "Bonus Child" Relationship

One of the most heartwarming parts of Jack's story is his bond with Tom Brady's ex-wife, supermodel Gisele Bündchen. Despite the divorce, Gisele has maintained a close relationship with her stepson, whom she famously refers to as her "bonus child." In recent interviews, Gisele has given rare insights into their relationship, often sharing gushing birthday tributes and highlighting the deep love and connection they share. This harmonious dynamic is the foundation for the blended family, which includes Jack's younger half-siblings, Benjamin and Vivian, whom he is very close to. The ability of all three parents—Tom, Bridget, and Gisele—to prioritize Jack's well-being has become a modern model for successful celebrity co-parenting.

What’s Next for John Edward Thomas Moynahan?

As Jack enters the critical final year of high school, the world is waiting to see which path he chooses. Will he follow the family legacy into the NFL, where his father is the undisputed GOAT (Greatest Of All Time)? Or will his surprising height and recent training with an NBA star lead him to the basketball court? The fact remains that John "Jack" Edward Thomas Moynahan has the genetics, the resources, and the drive to succeed in any field. He is currently focused on academics and training, keeping his options open. For now, he is a young man defining his own identity, one that is proving to be much taller and perhaps more surprising than anyone anticipated. His journey is a testament to his own talents, separate from the shadow of his famous last name.
