Liam Neeson on ‘strange’ sex scene with Pamela Anderson in ‘The Naked Gun’

They did the deed.

Liam Neeson and Pamela Anderson, who are allegedly dating, filmed a sex scene in “The Naked Gun” that involved Neeson’s first time working with an intimacy coordinator.

“There’s a threesome,” Neeson, 73, said on “The Late Show with Stephen Colbert” on Wednesday.

“And one of the participants is very cold,” the “Taken” actor added.

Neeson also described the experience with the intimacy coordinator as “a little bit strange.”

“Telling you how to do it?” Colbert, 61, asked.

“Pamela and I knew…,” Neeson replied, as the audience laughed.

When Colbert asked if the actors knew “how to bring in a third,” Neeson told the host, “No. That was a first.”

“That had to be specifically choreographed,” Neeson added.

Later in the interview, Neeson gushed over his rumored girlfriend.

“She’s great. She’s terrific,” he said about Anderson, 58.

News broke Tuesday that Neeson and Anderson are dating after striking up chemistry while filming “The Naked Gun.”

A source told People that the pair’s “budding romance [is] in the early stages” and that they’re “enjoying each other’s company.”

“It’s sincere,” the insider added, “and it’s clear they’re smitten with each other.”

Neeson and Anderson have been packing on the PDA throughout their press tour.

They pretended to make out during their Tuesday appearance on “Today” and Anderson kissed Neeson on the cheek at the film’s London premiere last week.

“I had never met Pamela before. We met on set,” Neeson said on “Today.” “And we discovered we had a lovely budding chemistry as two actors.”

“It was like ‘Ooo, this is nice, let’s not mold this. Let’s just let it breathe,’” he added. “And that’s what we did.”

The “Star Wars” actor also told People in October that he was “madly in love” with Anderson.

“I can’t compliment her enough, I’ll be honest with you,” he continued. “No huge ego. She just comes in to do the work. She’s funny and so easy to work with.”

Anderson, for her part, recently told Entertainment Weekly: “I think I have a friend forever in Liam, and we definitely have a connection that is very sincere, very loving, and he’s a good guy.”

In “The Naked Gun,” Anderson and Neeson play love interests. He stars as Lt. Frank Drebin Jr., the son of Leslie Nielsen’s Frank Drebin from the original films, while Anderson plays femme fatale Beth.

The movie hits theaters on Friday, Aug. 1.
