Bradley Cooper Plays with Pearl Jam, Hangs with Gigi Hadid at BottleRock

Bradley Cooper‘s proving the star wasn’t just born, but alive and kicking … ’cause he hopped onstage to perform a hit song from his 2018 movie — alongside a rock legend.

The actor put on his singing cap Friday night at BottleRock musical festival in Napa Valley … performing the song “Maybe It’s Time” from “A Star Is Born” with Pearl Jam’s Eddie Vedder.

Check out the clip … it’s a pretty intimate moment for such a massive concert experience — with Eddie and Brad sitting in chairs while Vedder shreds on an acoustic guitar.

If you don’t know … BC and EV have been friends for years — and, Vedder actually partly inspired Cooper’s ‘Star Is Born’ character. Bradley revealed in an interview during the movie’s press tour he spent multiple days with Vedder and asked him a ton of questions to hone his character.

BTW … Cooper also hopped onstage at the end of the set to sing Neil Young‘s “Rockin’ in the Free World” — two Bradley songs for the price of one!

It wasn’t all work and no play for Bradley though … ’cause he spent some quality time with his lady love Gigi Hadid — laughing and dancing while Stevie Nicks performed.

It looks like Gigi tried to keep a low profile in the hat and glasses — but, Bradley’s pretty out there, not covering up whatsoever. No point in going incognito when you’re jamming with the band later on anyway, we suppose.

BottleRock’s bringing out the A-List’s best and brightest FWIW … Cameron Diaz and Tommy Lee are both reportedly coming out for the weekend — and, Bradley even got to share the stage with Golden State Warriors star Steph Curry. Talk about star-studded.

BottleRock’s final day kicks off Sunday, and acts like Ed Sheeran, Queens of the Stone Age, Dominic Fike, The Offspring, Norah Jones and Stephen Marley are ready to hit the stage.
