Austin Butler has never been more “starstruck” than he was at Paul McCartney’s recent house party.

Taylor Swift was among the A-list guests at the shindig, according to Butler, 32, who recalled the experience on the Monday, June 17 episode of Jimmy Kimmel Live!.

“Last time I saw you was at maybe the craziest party I’ve ever been to in my whole life,” Kimmel, 56, told the Elvis star.

“That was insane,” said Butler of the event held at the home of McCartney, 82. “Do you want to list some of [the guests]?”

“It was a party where, like, Tom Hanks is going, ‘Oh, my God, can you believe who’s here?’ Right?” responded Kimmel. “The living Beatles, the living [Rolling] Stones, Mick Jagger, Bruce Springsteen.”

“To see Paul and Ringo [Starr] in the same room was kind of amazing,” Butler said with a smile. He also recalled how Springsteen, 74, told him a story about writing a song for Elvis Presley and sneaking onto the King’s property to convince him to record it.

Swift, 34, “was DJing at one point,” he revealed, without specifying what tunes the Grammy winner was spinning. “She has to DJ at parties now.”

Asked who he was most starstruck by — the Dune: Part Two star quipped to Kimmel, “besides you!” — Butler picked Meryl Streep. “She’s just the greatest. You know in high school, when you have a crush on somebody and they’re across the room and you don’t know how to say hello to them? That’s how it was.”

Butler then “went into Paul McCartney’s kitchen and ate some of his vegan pizza,” he recalled. When a friend insisted on introducing him to the 74-year-old Oscar winner, he added, “I couldn’t believe I was meeting Meryl Streep with Paul McCartney’s vegan pizza in my mouth.”

In the late-night interview, the Oscar nominee also recalled another memorable party — having “tacos with Snoop Dogg and Robert De Niro” — and shooting his new film The Bikeriders.

Among Butler's upcoming projects is Ari Aster's Eddington, costarring Emma Stone and Pedro Pascal.

The Bikeriders opens in theaters on Friday. Butler plays a member of a 1960s motorcycle club in the Jeff Nichols movie costarring Jodie Comer, Tom Hardy, Michael Shannon and Norman Reedus.
