Touched by his co-star's gesture, Steve, 67, shared his gratitude for Bridget. "Thank you my friend hope things are well!!!" he replied.

While Blue Bloods will conclude this fall, the cast and crew have forged unbreakable bonds on set. While appearing on The Drew Barrymore Show in April, Bridget and Donnie Wahlberg broke their silence on the show's cancellation.

Asked how they were feeling, Bridget, 53, remarked, "I think everybody's really upset and sad, but also happy and satiated?" before Donnie, 55, chimed in. "More upset and sad," he declared.

"I think it's more saying goodbye to the people behind the characters," continued Bridget.  "We've created such a family on set with each other and the crew — most of the crew's been with us for 14 years, so we've been through a lot of weddings, births, deaths, and everything. We've been through it all with each other."

Filming for the fifth and final season took place over the summer, with Donnie – aka Danny Reagan – sharing a clip from the set.

"I've taken this walk thousands of times in 14 years and it was a teary final walk from the Blue Bloods dinner scene, last week. More so than I could have ever imagined. Of course some sad tears — but mostly tears of immense humility," he began.

"It's been a wonderful adventure. One that I know so many of us, and so many of you, wish could continue. My desire to carry on, however, is only surpassed by the amount of humility I feel for having been part of this wonderful journey at all.

Donnie concluded: "I'm so thankful. None of it came easy, but nothing good ever comes easy — and none of it would ever occur if we don't allow ourselves to believe that our dreams can become reality. Nor would it happen without the support greatest fans ever, the greatest crew ever, in one of the greatest cities ever and one of the greatest law enforcement departments ever. Thank you Blue Bloods faithful. Til we meet again."
