Austin Butler says spending time with his “hero” Robert De Niro made him opt not to get high with famous cannabis connoisseur Snoop Dogg.

During a stop on “Jimmy Kimmel Live!” on Monday, the “Elvis” actor was asked for the story behind photos of him and the Oscar winner hanging out at the rapper’s Malibu home in March.

“That was wild,” he said of the Instagram snapshot posted by Snoop’s son Cordell Broadus.

“A mutual friend said, ‘Do you want to come ... have tacos with Snoop Dogg and Robert De Niro?’ and I dropped everything, and I was there in a heartbeat.”

Host Jimmy Kimmel had to ask Butler if Snoop, a seasoned pot smoker, “offered” him “anything” to toke on during the get-together.

“He had it there,” Butler admitted. “I was so nervous to get too high and try to talk to my hero Robert De Niro, so I refrained.”

Butler has long talked about his admiration for De Niro.

In a piece for A.frame, the Academy of Motion Picture Arts and Sciences’s digital magazine, last year, he called “Raging Bull” one of the films that shaped his entire approach to acting.

“The dedication that he had to that part is so endlessly inspiring to me,” one of the stars of “Dune: Part Two” wrote.

“The freedom that I see when I watch him, the subtlety that he can have, and then, moments of explosion. ... I cannot take my eyes off of him.”
