Having showcased his Adonis-like abs in every film from “Thelma And Louise” to “Fight Club,” Pitt seems like he’s perennially shirtless on-screen.

In fact, “Once Upon A Time In . . . Hollywood” director Quentin Tarantino claimed the 56-year-old Hollywood hunk’s a “master” at going topless. He dished the dirty details while discussing the star’s iconic shirtless scene on Tuesday’s episode of Amy Schumer’s podcast “3 Girls, 1 Keith.”

“In public Brad is kind of shy about stuff like that,” Tarantino tells a delighted Schumer and company, before adding, “at the same time he knows exactly what time it is.”

The “Pulp Fiction” auteur recounts the scene where Pitt’s character Cliff Booth expertly bares his bronzed upper torso while on a sun-drenched Los Angeles rooftop in what the director calls “the closest to homoerotica” he’s ever filmed.

Tarantino and Pitt share a laugh behind the scenes.

Brad Pitt won the 2020 Best Supporting Actor Oscar for his turn as stuntman Cliff Booth in “Once Upon A Time In… Hollywood.”

“I’m thinking maybe unbutton the Hawaiian shirt, and you peel that off the Champion T-shirt,” recalls Tarantino about the behind-the-scenes process.

However, the exhibitionist Oscar-winner apparently balked at the idea: “Really? You want me to go through all that button bulls - - t? I’ll just take it off in one big go!” Tarantino recalls him saying.

So, Tarantino “let the master do his job,” he said.

It appears that Pitt’s cinematic striptease paid dividends. Along with almost every other major award, the evergreen heartthrob won the 2020 Best Supporting Actor Oscar for his turn in “Once Upon A Time,” marking the first time Pitt’s ever taken home Academy gold.

If only the ab-flexing icon could give Tarantino such a glowing compliment. While presenting his “Once Upon a Time” director with a New York Critics Film Circle award in January, Pitt memorably joked of Tarantino that “he needed cocaine to stop talking.”
