After 11 years on the CBS police drama Blue Bloods, Tom Selleck may be ready to turn in his badge — and quit Hollywood for good.
"He's tired of the grind, and the show just takes more and more out of him every season," an insider tells OK!.
While producers have bent over backward to keep the 76-year-old happy by shooting his scenes first so he can hurry back to his beloved Ventura County, Calif., ranch, "it's still not enough," adds the insider.
Selleck, who's married to actress Jillie Mack, 63, and has two adult kids, "has always said he was more of a family man than a Hollywood star. He wants to spend more time with them."
The Magnum P.I. alum has a memoir set to come out in April, "and he sees it as a fitting end to an era," adds the insider. "The cast and crew will be sad to see him go, but Tom's got plenty to keep him busy — and he looks forward to kicking back on the days he doesn't!"
According to the insider, Selleck's been proud of what he's achieved being in showbiz for more than 50 years.
He has also managed to find some closure with Blue Bloods. Speaking to PEOPLE, the Detroit native revealed that his time on set has been some of his "most cherished" and that he loves working with his fellow actors.
"Our dinner party scenes are like a reunion of friends," the actor revealed. "Sometimes it's hard for the directors to get us to concentrate. We do the work, and we do it well, but we're also screwing around and kidding each other and catching up. What we have is truly a blessing."
