The Coachella music festival has kicked off with surprise guest actor Susan Sarandon featuring in pop star Sabrina Carpenter's headlining performance on Friday.
The actor delivered a monologue as an older version of 26-year-old Carpenter in the middle of her set. Other stars who featured in the singer's classic Hollywood-themed gig were comedian Will Ferrell and actor Sam Elliott.
The massive festival in the California desert draws more than 100,000 people daily over two weekends, according to police from the city of Indio.
This year, weather agencies have warned of wind and dust in the area, with strong winds forcing the festival to cancel a set by DJ Anyma after Carpenter's performance.
To kick off the globally renowned festival, Carpenter - headlining for the first time - turned the stage into the Hollywood Hills, nicknaming it Sabrinawood.
She began her set by appearing in a short film where she was pulled over while driving at night by the actor Elliott. He lets her go, and afterwards she emerges on stage. Comedian Ferrell appeared later on stage pretending to be an electrician.
Other performers on Friday included global girl group KATSEYE and British artist Disclosure. On Saturday, Justin Bieber will headline the festival, followed by Karol G on Sunday.
