NEW YORK — Liam Neeson is giving fans a peek at the threesome he filmed “terrific” new girlfriend Pamela Anderson in their “Naked Gun” reboot.

Neeson, 73, told “The Late Show with Stephen Colbert” of both the domestic and less demure acts he and the 58-year-old “Last Showgirl” star took part in while filming the fourth installment in the Leslie Nielsen-led comedy trilogy.

“There’s a threesome. … And one of the participants is very cold,” said the Oscar nominee-turned-action star.

The scene marked his first experience with an intimacy coordinator, which Neeson found “a little bit strange. … Pamela and I knew what…”

“You guys knew what to do?” laughed host Colbert, 61. “But did you know how to bring in a third, or was that old hat for you?”

“That was a first,” laughed Neeson. “That had to be specifically choreographed.”

Neeson also dubbed his leading lady — who in 2024 released her cookbook, “I Love You: Recipes from the Heart” — “great in the movie” and “terrific” overall.

“She made me sourdough loaves during the shoot, bran muffins, which I love,” said Neeson.

During the interview, Colbert also showed the crowd a clip the “Baywatch” star posted of the actors on a boat in Berlin, during the press tour.

“There’s a front of the boat and we thought, ‘Well let’s redo “Titanic,” you know?’ And Pamela was away in front of me, in the front of the boat. But the top of the boat was here [motions to his forehead], so I couldn’t get in, but I had to look after her,” said Neeson.

A source told People earlier this week that the actors are “enjoying” their “budding romance in the early stages,” and are currently “smitten with each other.”
