he boys in blue are back — well some of them, anyways.

As rumors run rampant that “Blue Bloods” star Tom Selleck might make a cameo appearance on the spinoff, “Boston Blue,” actor Mika Amonsen is remaining tight-lipped.

While Amonsen — who plays Selleck’s grandson on the spinoff series — told Page Six he has never met or spoken with the actor, he teases that a cameo conversation “was definitely there, for sure.”

Selleck was outspoken about his displeasure with CBS for canceling “Blue Bloods” in 2024 and has expressed hesitation about appearing on the new series.
