The beginning of the end of Blue Bloods starts on Friday, October 18, with the first of the last eight episodes of the long-running CBS drama, but the possibility of this world expanding has come up since news of its cancellation.

"Blue Bloods" star Donnie Wahlberg gave fans a glimpse of what they can expect for the crime drama's series finale after 14 years. Wahlberg shared the emotional moment he shared with co-star Tom Selleck.

“Blue Bloods” stars Tom Selleck and Donnie Wahlberg got emotional while they were filming the ending of their long-running procedural. “On the last day, I was filming all my squad room scenes and it’s kinda like where I hold court as Danny Reagan, and Tom Selleck came in just to watch,” Wahlberg said on SiriusXM’s “Andy Cohen Live.”
