Donnie Wahlberg, star of BLUE BLOODS, took to social media to pay tribute and express his love for his beloved co-star.
Blue Bloods, a CBS hit drama, followed the Reagans, an Irish Catholic family who all work in law enforcement. Donnie Wahlberg, who played Danny Reagan, took to Instagram to wish his on-screen father Tom Selleck a happy birthday.
Wahlberg captioned two photos of himself with Selleck with a moving tribute to the legendary actor.
"Happy Birthday to my TV dad, and real-life friend and father figure, Tom Selleck!" it said.
"I'm grateful to have you in my life, 'dad,' and feel blessed to play a small part in the amazing legacy that is your life!" Dad, I adore you! Every time, Son!"
"(ps, I know you won't see this because you probably don't know what @instagram is, but that's fine because I don't mind sharing with the world that you mean a lot to me)."
The two have shared a screen since Blue Bloods first aired in 2010, and after 12 seasons, neither actor has shown signs of slowing down.
Despite initial speculation about Selleck's departure, the 77-year-old actor seemingly told People.com that he'd play Frank Reagan until the end of the show.
"I don't think there's an endpoint, I think there's a lot of life in the show, as long as you let your characters grow and get older," he said.
Despite the fact that his character was offered a new role outside of the NYPD, this is exciting news for fans of the beloved police commissioner.
