When Blue Bloods first premiered in 2010, viewers instantly connected with the Reagan family and their strong values, gritty cases, and Sunday dinners. Now, in 2025, the cast has become a staple of television history. But time doesn’t stand still—even for fan-favorite stars. Their transformations over the years may surprise even the most loyal viewers.

Tom Selleck, the heart and soul of the series, still carries himself with the same gravitas at 80. Though slower-moving and more selective with his scenes, he continues to portray Commissioner Frank Reagan with dignity and quiet strength. His signature mustache hasn’t gone anywhere, but fans can see the years gently catching up. Bridget Moynahan (Erin) remains as elegant as ever at 54, balancing her career on screen with real-life advocacy work.

Donnie Wahlberg, always the energetic Detective Danny Reagan, has embraced his age with style—grayer hair and a more reflective demeanor both on and off camera. Will Estes (Jamie) and Vanessa Ray (Eddie) have matured visibly too, with Will taking on more behind-the-scenes roles in recent seasons. Their chemistry continues to shine, but they’ve clearly evolved since their early days.

Looking back at the Blue Bloods cast in 2010 compared to now feels like revisiting old friends. Their appearances may have changed, but the core of who they are—and the impact they’ve had on fans—remains just as powerful. 2025 has brought new depth, wisdom, and appreciation to the faces we’ve watched for 15 seasons and counting.
