Mark Wahlberg congratulates brother Donnie on Blue Bloods run

Mark Wahlberg and Donnie Wahlberg are among the most successful brothers in Hollywood. They have spent the last several decades dominating film and television, with Mark doing the former and Donnie achieving the latter through Blue Bloods. It's rare, however, for the brothers to discuss each other's work.

That's what made Mark Wahlberg's recent comments so surprising. During an interview with ET, the Oscar nominee praised Blue Bloods, and the performance of his brother, Donnie, in particular:

""[Congrats], of course, to Donnie, Tom [Selleck], the whole cast! [It's] remarkable! It really is an unprecedented run. [As] somebody who's been producing television for a long time, [I know] it's not an easy feat. So, congratulations! It's quite an achievement.""

Mark and Donnie has spent the last decade as a close-knit duo, but during a 2015 appearance on Howard Stern, the latter admitted that there was a period in which they didn't speak to each other very often. The reasoning? Both were busy in their respective careers.

Mark Wahlberg called Blue Bloods a TV "achievement"

"It wasn’t personal," Donnie explained. [I understand if] Mark wants to spend that day with his daughter instead of spending it with me and my wife." The thing that brought them back together was, conveniently, television. The two men agreed to star in the reality series Wahlburgers, which detailed their efforts to run a fast food franchise.

The series ran from 2014 to 2019, and featured other members of the Walhberg family, was a surprise hit on A&E. Donnie Wahlberg credited most of the success of Wahlburgers to the bond between him and the rest of the family, which is an aspect he's also proud of in Blue Bloods. In an interview with ET, the actor praised the police drama's ability to juggle crime and family concerns.

"I have a great cast, who’s become family, we have a great crew and so many loyal viewers and fans. It’s just unbelievable," he added. So it’s not that I feel relief as much as I kind of have to pinch myself sometimes and go, like, how did this happen? I just feel so blessed and so grateful."

Donnie has been keeping fans updated on the making of Blue Bloods season 14 on Instagram, and assures fans that they will be getting the send-off they deserve after nearly a decade and a half.
