The Oscar-nominated actor made appearance on the Today show Thursday, where he revealed that a run-in with the Barbie star made him so nervous that he couldn’t even introduce himself.

“I was just telling a story yesterday about getting starstruck by Ryan Gosling recently. It’s when you don’t expect to see somebody — so I saw him outside of a hotel that I was staying in, and I had to go into another door,” Butler recalled. “I couldn’t even say hello. Because I grew up admiring him so much.”

When host Savannah Guthrie reminded the Elvis actor that he’s also a star, he responded, “I know. But that doesn’t feel real.”

Gosling wasn’t the only Hollywood notable that Butler has been captivated by. He also recalled attending a star-studded party recently, hosted by Paul McCartney.

He revealed on Jimmy Kimmel Live! earlier this week that Taylor Swift, Tom Hanks, Mick Jagger, Bruce Springsteen and Ringo Starr were among those in attendance.

“Some people I know — Paul I’ve met a couple times. He’s so sweet,” the Dune: Part Two actor told Guthrie before revealing another starstruck moment. “I had never met Springsteen, so that was really… Those are those moments that you just, you can hardly fathom the amount of talent that’s surrounding you.”

While Butler is already well-known in Hollywood, with many acting credits to his name, he’s still very appreciative of the success he’s received throughout his career.

The Masters of the Air star said, “I’ve been acting for 20 years, and most of that time you just try to pay the rent and pay for gas, so right now I just feel very grateful.”
