Pearl Jam made an uncommon appearance as a headliner at the 2024 BottleRock Napa Valley in California, United States. Bradley Cooper unexpectedly appeared on stage as a surprise guest. The 49-year-old actor welcomed the crowd and performed the song ‘Maybe It’s Time’. The country ballad tune is part of the soundtrack for the film ‘A Star Is Born,’ in which he stars with Lady Gaga.
