Tom Selleck Feels Betrayed as Donnie Wahlberg Steals His Spotlight with Blue Bloods Spinoff

Blue Bloods alum Tom Selleck is seeing red over the ultimate betrayal — former costar and protégé Donnie Wahlberg is stealing his beloved TV show!

The 80-year-old former Magnum, P.I. star bitterly fought CBS execs to keep his hit show Blue Bloods on the air — and lost. Now sources say he hit the roof when he learned Donnie will be the star of the show’s just-announced spinoff, Boston Blue.

The new series will reunite viewers with Donnie’s character, NYPD officer Danny Reagan, as he moves to the Hub and joins the Boston police department, where he’ll team up with detective Lena Peters, a character from a prominent law enforcement family.

“This is a HUGE betrayal,” says a source. “The Reagans never left New York. Now Danny’s just up and moving to Boston? Selleck is furious — it’s like throwing the rest of the cast away, including the star!”

While Wahlberg’s deep Boston ties make the setting a logical fit, critics say the whole enterprise feels more like a reboot than a spinoff — and Selleck isn’t fooled!

“Tom considered himself this father figure to Donnie and helped him with his acting skills, and now he’s found out everything going on behind his back. It’s a huge burn,” squeals a source. “He feels a sense of betrayal and is furious over the news.

“Friends are saying he had no clue this was even in discussion. He’s putting on a brave face, but make no mistake — he’s still hoping for word that he’ll be needed on this new show!”

An insider adds that Tom believes CBS is making a huge mistake, and that it just proves they were looking for a way to move on without him and his hefty salary when they shuttered the show.

Publicly, Donnie, 55, has had nothing but praise for Selleck, calling him “a great mentor.”

But insiders say this is an example of the ultimate Hollywood backstab, and sources claim Donnie had the power to stop it — but chose to take the payday over loyalty to his longtime friend.

“Donnie could have refused to move forward without Tom,” snipes the source. “But he didn’t, and Tom will never forgive him for it.

“This is the end of Tom and Donnie’s on-screen and off-screen friendship for good!”
