It was time for Jackson Maine to make his return to the stage.

On Saturday, May 25, Bradley Cooper joined Eddie Vedder — who famously inspired his A Star Is Born character Jackson Maine — onstage at BottleRock Napa Valley food and music festival in Napa, Calif. for a surprise duet of "Maybe It's Time" from his 2018 film.

"Please, would you join me in welcoming to the stage my great, great pal Bradley Cooper," the Pearl Jam frontman, 59, told the crowd during the band's headlining set at the music festival in a fan-posted video.

From there, the Maestro actor, 49, gave Vedder a kiss on the cheek and sat onstage next to him as he strummed the acoustic guitar as the pair traded verses.

On Monday, May 26, Pearl Jam shared an Instagram post that featured the "Last Kiss" artist hugging Cooper behind a copy of the set list, which featured the collaboration between the pair.

"Cheers, @bottlerocknapa! 🍷🌅," the caption read.

In a 2018 interview with Yahoo! Entertainment, Cooper revealed that the "Just Breathe" musician was, in fact, the inspiration for his A Star Is Born alter-ego.

“I went up to Seattle and spent four or five days with him and I asked him 9,000 questions,” the actor/director told the outlet. “And he gave me minor, little things that only musicians know about what to do, just aesthetically and the inner workings.”

However, Vedder was initially skeptical of Cooper's decision to sing on-screen.

“He was like, ‘What? Bro, don’t do that,’ ” he recalled.

But eventually, the rocker passed along notes for the songs in the movie.

“He was wonderful,” Cooper said.

Also on Saturday, May 25, the Silver Linings Playbook actor got behind the grill to make his famous Philly cheesesteaks, which were Gigi Hadid-approved!

The supermodel, 29, who has been romantically linked to Cooper since October 2023, was spotted devouring the regional dish on the second day of the Napa Valley music festival.

The sandwich was prepared by the 12-time Oscar nominee who was at the event with Angelo's Pizzeria owner Danny DiGiampietro for Danny and Coop's Cheesesteaks – which they teamed up to open in 2023.

The Culinary Stage at the festival had a lineup teeming with high-profile celebrities, including Neil Patrick Harris, his husband David Burtka, Cameron Diaz and Katherine Power for their organic wine company Avaline Wine, and basketball champ Stephen Curry for his bourbon line Gentleman's Cut Bourbon.

On the stage, Cooper was also seen showcasing his basketball moves with Curry, 36, as they tossed cheesesteaks into the crowd.
