The cast of Blue Bloods doesn’t just play a family on TV, they’ve become a tight-knit group since the show first premiered in 2010. The CBS series follows the lives of the Reagan family led by Tom Selleck’s steward, Frank Reagan. Frank’s father, Henry Reagan (Len Cariou), sits across from him at the group’s weekly Sunday (…)

Selleck’s right hand, or rather wife, of the series Abigail Hawkwho played 1PP secretary and ex-cop Abigail Baker, didn’t let the day pass without sharing some birthday memories via social media.

“Happy birthday, boss!” Hawk, 43, wrote via his Instagram story about a group photo from years past.

The image, which included balloons floating above the cast, was set to New Kids on the Block’s “Happy Birthday.”

The song choice was a nod Blue blood cost and now Boston Blue lead Donnie Wahlbergwho played Frank’s son Danny Reagan and is a member of the 90s boy band.

“I wish you more laughs like this!” Hawk wrote alongside another photo with Selleck and a former castmate Robert Clohessywho portrayed another 1PP member of Frank’s team, Sid Gormley.

Hawk added another Easter egg to the second photo, this time with a sticker of his own from Selleck Magnum P.I days with the word “moustache” written next to it. (Selleck was famous for his sexy mustache while playing private investigator Thomas Magnum on the CBS show from 1980 to 1988.)

Both Moynahan and Hawk formed a close bond with Selleck while starring Blue Blood. The procedural premiered in 2010 on CBS and followed Selleck’s Frank Reagan and his family of first responders.

In addition to Frank being the current police commissioner, his father, Henry Reagan (Only for Caria), was his predecessor. Frank’s three living children—his eldest son Joe was killed in the line of duty—are dedicated to helping others.

Son Danny (Wahlberg) is an NYPD detective, while Erin (Moynahan) works in the district attorney’s office before becoming the ADA. His younger brother, Jamie (Will Estes), studied law, but chose to become a policeman like his brothers and father.

The show lasted 14 seasons with nearly 300 episodes and at its core was a series about family. (On Sundays the Reagan they all had dinner togetherwithout fail.)

Before the series finale, which aired in December 2024, Moynahan explained exclusively Us Weekly this Blue blood it was “more than just a job. It was an important part of all our lives.”

Hawk, meanwhile, explained exclusively we in December 2024, getting to know the man behind the mustache, aka Selleck, so well was one of the greatest blessings of playing one of his employees on the show.

“I just think for someone who is the literal embodiment of, like, the Marlboro Man (aka the smoking cowboy) and the Brawny Man (a lumberjack figure) and (a) mustachioed icon that a lot of us are like, ‘That’s a man,'” Hawk said of the public’s perception of Selleck.

He revealed that at his core, Selleck “loved his mother” and often reminisced about his childhood to her and his cast mates.

“Just looking forward to seeing these little snapshots of the man behind the legend is what I value most about him,” Hawk added.

Since the series went off the air, the spin-off show Boston Bluewhich follows Danny’s life in Boston after he moves from New York to care for son Sean (now played by Mika Amonsen) as he begins his career as a cop in Beantown, has given Blue Bloods a slice of the beloved OG series.

Moynahan is among the original cast members who has made a cameo in the sequel program – with more to come.

Boston Blue returns with new episodes on CBS Friday, February 27 at 10:00 PM ET. New episodes will stream the next day on Paramount+.
