During the filming of the final dinner scene on 'Blue Bloods,' Donnie Wahlberg broke down in tears and couldn't stop crying.

The final dinner scene of "Blue Bloods" was challenging for the cast, including Donnie Wahlberg and Tom Selleck, to film.

In a recent interview with Entertainment Weekly, Wahlberg shared his emotional experience of working together for the last time.

During the finale, we were all walking a delicate tightrope, feeling emotional each day and knowing it was the last episode.

The 55-year-old actor, who was once a boy band star, predicted that the show's finale may be emotional for its loyal viewers. The final dinner scene between the NYPD family and detectives, led by Selleck, could make fans as emotional as the cast was, he said.

"They may be feeling conflicted by emotion because it is the last episode," he said. "We definitely went to work every day knowing it was the last episode and tried to hold back the tears and the emotion, and the audience will probably do the same."

On Friday, Dec. 13, the final episode of "Blue Bloods" will be shown on CBS.

"I'll remember most the moment we finished filming," Wahlberg stated. "We all sat for a long time, and everyone was hesitant to say goodbye because A, nobody wanted to, and B, everyone knew once someone started talking, it was over."

Donnie Wahlberg, the star of 'Blue Bloods,' will miss the cast and crew the most after the upcoming final season.

"Everyone started crying as the tissues came out."

During the 14-season run of the show, Selleck frequently recited poems, and this time the emotional impact was even stronger, as Wahlberg stated.

"We commenced filming with the dinner scene on our first day, right? At that moment, I was too preoccupied with being in awe of Tom Selleck to contemplate, "Wow, when I was a child, if someone had informed me I would collaborate with Tom Selleck for 14 years - or ever - it would have been beyond my wildest dreams." Now, as we conclude our 14th year of working together, I allowed myself to reflect on this while Tom was speaking."

For a few hours, he couldn't stop crying.

Selleck's presence on television during the narrator's childhood brought about much of the emotion experienced while working with him.

Selleck spoke before Wahlberg, who struggled to express himself.

"I may not have the exact words, but I believe I did my best to express how much the crew meant to me, and that despite the difficulty of saying goodbye during a challenging time, I encouraged everyone to remember the luck of being part of such a special opportunity. If there's anything that can make you feel better about the end of a special opportunity, it's the fact that you were fortunate enough to be a part of something so special in the first place. That's where I tried to focus, and that's how I approach it every day."

In October, Wahlberg stated that he believes the audience will be content.

He shared on Sirius XM Andy Cohen Live that it felt like a finale, but a hopeful and forward-thinking one.
