Bridget Moynahan is joining her brother in blue.
The 54-year-old actress is officially set to reprise her role as Erin Reagan in the “Blue Bloods” spinoff, “Boston Blue.”
The new series will follow Danny Reagan (Donnie Wahlberg) as he leaves New York City to take a position with the Boston Police Department.
“Blue Bloods” premiered in 2010, centering on a New York City family dedicated to law enforcement. The star-studded cast included Tom Selleck, Will Estes, and Len Cariou as key members of the close-knit family.
CBS announced on Friday that Bridget Moynahan will guest star in the first episode of “Boston Blue” and is also slated to direct an episode in Season 1.
“Reunited and it feels so good!” Wahlberg, 55, wrote in an Instagram post featuring his longtime co-star on set. “So excited to have my dear friend and TV sister @bridgetmoynahan join me for a special guest appearance in the premiere episode of #BostonBlue!”
“She’ll also be bringing her incredible directing talents to the show this season!” Wahlberg added. “More fun (and surprises) to come. Let’s go!”
On July 8, the “Very Scary People” host shared a photo on his Instagram Stories from his first table read for the spinoff.
“A new chapter,” Wahlberg wrote beneath a snap of the pilot script.
Also joining the cast of “Boston Blue” is Sonequa Martin-Green, who will play Detective Lena Silver, Danny Reagan’s partner.
The cast is rounded out by Maggie Lawson, Marcus Scribner, Gloria Reuben, and Ernie Hudson.
Earlier this month, CBS announced a recast for Danny Reagan’s son, Sean Reagan, despite Andrew Terraciano having portrayed the character in nearly every episode across 14 seasons.
Now, Mika Amonsen will take over the role of the youngest Reagan, who moves to Boston with his father. Sean will serve as a patrolman for the Boston Police Department, according to Deadline.
“Blue Bloods” aired its series finale in December after 14 seasons on CBS.
At that time, Donnie Wahlberg wrote a heartfelt tribute to the police procedural and a love letter to the show’s devoted fans.
“Dearest Blockheads,” Wahlberg began on Instagram. “There is, of course, a sadness in saying goodbye to #BlueBloods. But what a heck of a ride we had together! You all were literally part of the Blue Bloods family! Not just on Friday nights (trending #BlueBloods every single week it was on the air), not just in your impact on the ratings (which was massive), you all made yourselves an actual part of the crew.”
He added that everyone on set “knew you, appreciated you, and was happy to see you.”
“None — more than me. Of all the memories, highlights, and moments that I’ll look back on fondly from the last 14 years of filming #BlueBloods in New York City, your set visits will be something that I’ll cherish forever,” he shared.
The New Kids On The Block member fondly recalled his cherished memories of the show’s viewers.
“You brought smiles, gifts, cupcakes (even though I was staying in shape for NKOTB tours), candy (too many Coffee Crisps and Kinder to mention), hugs, signs, inspiration, and of course love. Some visitors — did not miss a season,” Wahlberg shared. “Some visitors — we now miss so dearly.”
“I keep closing my eyes and seeing your faces as I’m writing this. I’m so thankful to you all. Please know that my heart is full. I could go on forever about you, but it’s time to stop writing and simply let these memories live. I thank you. I love you. I appreciate you. I salute you,” he concluded with a heartfelt sign-off.
“My Blockhead/BlueBloods Family. See you on the next adventure. Coming soon.”
However, Tom Selleck, 80, didn’t hide his frustration over the series’ end.
“I’m kind of frustrated,” the Emmy winner told TV Insider in October. “During those last eight shows, I haven’t wanted to talk about an ending for Blue Bloods but about it still being wildly successful.”
Selleck also noted that the show continued to have strong ratings.
“I’m not going to turn into a bitter old guy saying, ‘Get off my lawn!’ I don’t believe in holding grudges, but if you were to say to the television network, ‘Here’s a show you can program in the worst time slot you got, and it is going to guarantee you winning Friday night for the next 15 years,’ it would be almost impossible to believe.”
Selleck added, “My frustration is the show was always taken for granted because it performed from the get-go. So how do I feel? It’s going to take a long time to sort all of this out.”
Despite his disappointment, the “Magnum P.I.” star isn’t done yet.
He told Town & Country in May, “I hope there’s another Western in my future. Certainly whatever happens with ‘Blue Bloods,’ I’m not going to stop acting.”
That same month, Wahlberg revealed he did everything he could to save “Blue Bloods” before accepting the show’s end.
“When it ended, we thought, ‘Okay, some of the network’s gonna come and say, let’s keep going.’ And nobody came, and it was kind of like we were all in denial about it,” he told Fox News Digital.
Wahlberg said the opportunity to produce “Boston Blue” then presented itself.
“It was heavy, you know?” Wahlberg confessed. “It’s, like, how do I do this? Like, how does [his character] Danny Reagan carry on? You know, how do we create this new world for this character, and how do we do it in another city, not in New York?”
He shared how much everyone involved in “Blue Bloods” — both in front of and behind the camera — meant to him.
“They became part of our family,” he said. “You know, the viewers are saying, like, ‘How do we keep going with a Blue Blood spinoff without the whole family?’ And I share that. How do we do that, right?”
Ultimately, Wahlberg made the decision to move forward with the new project.
“It was definitely a challenge to take on this opportunity, but I kept saying to myself, you know, if I’m really sincere about wanting ‘Blue Bloods’ to carry on, here’s an opportunity to do it,” Wahlberg explained.
“Now, it’s just Danny going to this new world, but I can’t say a lot about it — but I can say, if he’s a Reagan, it will never be just Danny. There’ll always be a Reagan a phone call away. And the traditions that the Reagans have, Danny wouldn’t abandon those traditions.”
