Katy Perry, Rihanna, David Hasselhoff, Pierce Brosnan, Vanessa Hudgens, Jared Leto and Lindsay Lohan showed up Saturday, the final day of the 2012 festival to join the crowds taking in the music, EW reported.
Second-day headliners Radiohead pleased festival-goers with 20 songs of high-tech, hypnotic music to an enormous crowd that stretched half-way across the entire festival space.
They started their set with "Bloom" and finished up with "Paranoid Android."
Earlier, Noel Gallagher appeared on the main Coachella stage with his new band High Flying Birds, in support of his first album since his breakup with brother Liam and their band, Oasis three years ago.
A not-entirely-friendly crowd shouted question about the whereabouts of Liam, which Noel Gallagher chose to ignore as the band played through its set, ending with "Don't Look Back in Anger," which drew a cheer from the assembled fans.
