Pamela, on the other hand, plays a woman named Beth Davenport, with whom Frank becomes involved. The Naked Gun already being hailed as "the funniest movie of the year" ahead of its release on Aug. 1. And if it wasn't already obvious, it sounds like Liam and Pamela had a whole lot of fun making the movie - so much so, in fact, it may have even led to an offscreen romance, but more on that later. Tristar Media / Getty Images Appearing on The Late Show on Wednesday, Liam was asked by host Stephen Colbert about some of the movie's more intimate moments, including a scene where we see his bare ass - or what we're supposed to believe is his bare ass. CBS / Via youtu.be "I wish I could say it was mine. It's not. It's in the contract," the 73-year-old joked, clarifying that a "stunt" butt was used. For context, The Naked Gun was Liam and Pamela's first time working together. And it also happened to be Liam's first time using an intimacy coordinator to oversee his and Pam's spicy sex scene: an "unexpected" threesome.

Pamela and I knew [what to do]." CBS / Via youtu.be Hilariously, Stephen asked if Liam was as familiar with inviting a third into the bedroom, to which he responded: "That was a first. That had to be specifically choreographed." If one thing's for sure, Pamela and Liam have serious chemistry, which has only fueled interest in reports that the co-stars are enjoying a "budding romance in the early stages." "It's sincere, and it's clear they're smitten with each other," an insider told People this week, adding that they're loving each other's company.
